Chapter 1. Introduction to DAT/EM CAPTURE 1

Chapter 1. Introduction to DAT/EM CAPTURE

DAT/EM Systems International specializes in interfacing popular Computer Aided Drafting (CAD) and Geographic Information System (GIS) packages to mapping and surveying instruments.

About DAT/EM CAPTURE

DAT/EM CAPTURE™ is a stereoplotter interface to the user’s choice of Autodesk AutoCAD®, Bentley MicroStation®, or ESRI ArcGIS® packages, which are widely used commercial CAD/GIS packages. It provides direct communication between the stereoplotter’s 3D positioning and switches to the CAD or GIS software.

DAT/EM CAPTURE may be used with any analog stereoplotter with three axis encoders, or with one of a wide variety of analytical and digital stereoplotters.

All data collected with DAT/EM CAPTURE is fully three dimensional.

The DAT/EM mapping system offers these advantages in today's highly competitive digital world:

• Low cost for a complete stand-alone stereoplotter workstation

• Greatly reduced learning curve for system operators

• Regularly scheduled software updates

• Real-time on-line graphics for data capture and editing

• Push-button ease of operation

• DAT/EM KEYPAD accessory greatly speeds multiple or repeated command entries

About SUPER/IMPOSITIONSUPER/IMPOSITION™ will be mentioned throughout this manual. SUPER/IMPOSITION™ is sold as a video accessory for DAT/EM CAPTURE, or as a part of DAT/EM’s SUMMIT EVOLUTION™ digital stereoplotter. SUPER/IMPOSITION sends an image of digitized objects into the eye along with the usual photographic view given by the stereoplotter. On analog and analytical stereoplotters, a special video monitor and optical system are added to the stereoplotter. On digital stereoplotters, the additional graphics are added to the image view display.

• Digitized objects and optional coordinate text appear superimposed onto the images. This makes it easy to see digitizing progress and object accuracy.

• SUPER/IMPOSITION is excellent for map revision. When the older file is superimposed over an area of new construction, any new features are immediately obvious.

• The stereoplotter can check graphical objects without turning away from the image view.

Install DAT/EM CAPTURE and Configure AutoCAD 2

Review or Change the Application Loading MethodAn acad.rx file is provided with DAT/EM CAPTURE installation. This file contains a list of DAT/EM applications for AutoCAD to load every time it starts. However, some users prefer to change this installation default:

• To use the acad.rx file as it is originally installed, do nothing.

• To review or edit the acad.rx file, see “How to Load Applications from acad.rx” on page 2-11.

• To use the Startup Suite instead, see “How to Load Applications from the Startup Suite” on page 2-12.

• To disable loading, see “How to Prevent Automatic Loading, Then Load Manually” on page 2-13.

How to Load Applications from acad.rxAn acad.rx file is placed in the ...\ProgramFiles\AutoCAD(version)\Datem folder during DAT/EM CAPTURE software installation. As AutoCAD starts, it checks for an acad.rx file in the support file search path that was configured earlier in “Set the Support File Search Path and Pointing Device” on page 2-2. If the file exists, it automatically loads all the applications listed in the file.

You may wish to review or change the contents of the acad.rx file. Perform the following steps:

Step 1) Open the \Program Files\AutoCAD (version)\Datem\acad.rx file in any text editor such as Windows Notepad.

The DAT/EM application file names depend on the version of AutoCAD. Note that the names may not seem to match the version of AutoCAD, but that is normal. For example, files for both AutoCAD 2004 and AutoCAD 2006 are called (Filename)2004.arx. This simply means that there were no changes to the file for the higher version of AutoCAD.

Step 2) To add an application so that it loads automatically every time AutoCAD starts, enter its file name on a single line in the file. Some suggested files that may be included in acad.rx are (note that some applications are not provided with SUMMIT EVOLUTION LITE EDITION):

a.) Autolist(verison).arx, contains the autolist command.

b.) BlockRotate(verison).arx to rotate blocks in a drawing.

c.) Breaklinefilter(verison).arx contains the breaklinefilter command.

d.) Capture(verison).arx, contains the main DAT/EM CAPTURE interface and commands.

e.) CaptureContour(verison).arx, contains the CAPTURE CONTOUR option (if installed).

f.) CheckLineElevation(verison).arx, contains checklineelevation and other commands.

g.) Clenup(verison).arx, contains the cleanup command.

h.) ClipIt(verison).arx, contains the datclip command.

i.) DtmDistributor(verison).arx contains the dtmdistributor command.

j.) DtmEditor(verison).arx contains the dtmeditor command.

k.) DtmIt(verison).arx contains the dtmit command.

l.) MapEditor(verison).arx contains the MAP/EDITOR commands.

m.) Measure(verison).arx contains the measureheight and lineslope commands.

n.) Si(verison).arx, contains SUPER/IMPOSITION (if installed). If listing this application, list Capture(version).arx first, then list si(version).arx on the next line.

Install DAT/EM CAPTURE and Configure AutoCAD2

Step 3) To remove an application so that it does not load, delete the line containing that file name.

How to Load Applications from the Startup SuiteAn acad.rx file is placed in the ...\ProgramFiles\AutoCAD(version)\Datem folder during DAT/EM CAPTURE software installation. If AutoCAD finds the acad.rx file when it starts, it loads all the applications listed in the file. However, you may wish to use the AutoCAD Applications Startup Suite instead of acad.rx.

To use the Applications Startup Suite instead of the acad.rx file, perform the following steps:

Step 1) Rename ...\Program Files\Acad (version)\Datem\acad.rx file to acad.rx.deactivated. (Do not delete it, in case you want to use it again later.) After it is renamed, AutoCAD cannot find it.

Step 2) Start AutoCAD. Select Load Application from the Tools pull-down menu.

Step 3) Click the Contents button in the Startup Suite area.

Example acad.rx file to automatically load .arx files

Select Load Application from the Tools pull-down menu, then select the Contents button from the Startup Suite area.

• To add an application, select the Add button and choose the file.

• To delete an application, click on the file name to highlight it, then select Delete.

Install DAT/EM CAPTURE and Configure AutoCAD 2

Some suggested files that may be included in the Startup Suite are (note that some applications are not provided with SUMMIT EVOLUTION LITE EDITION):

a.) Autolist(verison).arx, contains the autolist command.

b.) BlockRotate(verison).arx to rotate blocks in a drawing.

c.) Breaklinefilter(verison).arx contains the breaklinefilter command.

d.) Capture(verison).arx, contains the main DAT/EM CAPTURE interface and commands.

e.) CaptureContour(verison).arx, contains the CAPTURE CONTOUR option (if installed).

f.) CheckLineElevation(verison).arx, contains checklineelevation and other commands.

g.) Cleanup(verison).arx, contains the cleanup command.

h.) ClipIt(verison).arx, contains the datclip command.

i.) DtmDistributor(verison).arx contains the dtmdistributor command.

j.) DtmEditor(verison).arx contains the dtmeditor command.

k.) DtmIt(verison).arx contains the dtmit command.

l.) MapEditor(verison).arx contains the MAP/EDITOR commands.

m.) Measure(verison).arx contains the measureheight, lineslope, and tinpolygons commands.

n.) MorphExporter(verison).arx contains the morphexporter command.

o.) Si(verison).arx, contains SUPER/IMPOSITION (if installed). If listing this application, list Capture(version).arx first, then list si(version).arx on the next line.

Step 4) When finished, close the Startup Suite and Load/Unload Applications boxes. The settings take effect the next time AutoCAD starts.

How to Prevent Automatic Loading, Then Load ManuallyThe user has a choice whether or not to load applications automatically. As a rule, if DAT/EM CAPTURE is used during the majority of AutoCAD sessions, then it is best to load the applications automatically. But if DAT/EM CAPTURE is not used often, you may wish to prevent automatic loading of some or all of its applications.

To prevent automatic application loading, perform the following steps:

Step 1) If currently using the acad.rx method to load applications:

• To stop using the acad.rx file, rename it to acad.rx.deactivated. (Do not delete it, in case you want to use it again later.) The file’s default installation location is: \Program Files\AutoCAD (version)\Datem\acad.rx.

• To continue using acad.rx, but to change the list of files it loads, edit \Program Files\AutoCAD (version)\Datem\acad.rx with any text editor such as Windows Notepad. See “How to Load Applications from acad.rx” on page 2-11.

Step 2) If using the Startup Suite to load applications, select Load Application from the Tools pull-down menu. Click the Contents button in the Startup Suite area. Delete any application names that should not be loaded when AutoCAD starts.

Chapter 3. Day-to-Day Use of DAT/EM CAPTURE 3

Chapter 3. Day-to-Day Use of DAT/EM CAPTURE

This chapter gives instructions and hints for digitizing, editing, and outputting with DAT/EM CAPTURE™.

How DAT/EM CAPTURE Affects the AutoCAD EnvironmentThere are several differences between using AutoCAD with a standard 2D digitizer and using AutoCAD with DAT/EM CAPTURE’s 3D digitizer. The most noticeable additions are as follows:

• With DAT/EM CAPTURE, there are two digitizers: the 2D mouse and the 3D stereoplotter. Read more about digitizer-related subjects in:

“Hints for Seeing the Cursor in a New Drawing File” on page 3-1“Cursor Control with System Mouse and Stereoplotter” on page 3-2

• The DAT/EM KEYPAD™, P-series tablet menu, pull-down AutoCAD menu, and toolbar menus all contain many useful DAT/EM CAPTURE utilities and digitizing aids. Read more about the menus in:

“Using the DAT/EM Menus” on page 3-2“Customizing the DAT/EM KEYPAD” on page 4-3

• DAT/EM CAPTURE provides commands to quickly digitize streamed and point-to-point 2D and 3D polylines and block symbols. Read more about these digitizing commands in:

“Digitizing Polylines with DAT/EM CAPTURE” on page 3-3“Digitizing Blocks with DAT/EM CAPTURE” on page 3-4Chapter 5, “DAT/EM CAPTURE Command Reference”

• In addition to the DAT/EM CAPTURE commands described in Chapter 5, all of the AutoCAD commands are available for mapping purposes. A good working knowledge of AutoCAD is valuable for efficient mapping. However, the beginning AutoCAD user will also be able use DAT/EM CAPTURE. Read more about helpful AutoCAD commands in:

“AutoCAD Commands that are Useful for Mapping Projects” on page 3-7“Using Layers to Separate Data” on page 3-7

Hints for Seeing the Cursor in a New Drawing FileIn a new drawing, the cursor may not immediately appear on the screen. The stereoplotter cursor position is in the model area, while the view displayed in a blank drawing file may not show the same coordinate range. When AutoCAD’s view is set to fit around the model area, the cursor will appear.

Even if the cursor is not on the screen, objects can still be digitized at the correct locations. AutoCAD is constantly updated with the current stereoplotter location, whether or not the cursor is in the graphics view.

To initially match the stereoplotter location and the AutoCAD display area:

1. Zoom with the stereoplotter

Zooming with the stereoplotter forces a new zoom center in AutoCAD. (Does not apply to analog stereoplotters.)

2. Turn on datpan

See “Datpan” on page 5-48.

DAT/EM CAPTURE for use with AutoCAD 3-1

Day-to-Day Use of DAT/EM CAPTURE3

Cursor Control with System Mouse and StereoplotterThe system mouse and the stereoplotter may be used alternately to move the cursor. Switching from one to the other is easy:

• For SUMMIT EVOLUTION LITE EDITION or when SUMMIT EVOLUTION is set to the System Mouse input device, right click in the main view to activate stereoplotter cursor control. Double right click to deactivate stereoplotter cursor control and switch back to regular system mouse mode.

• For all other stereoplotters and SUMMIT EVOLUTION digitizing devices, simply move the desired digitizer for it to obtain cursor control.

Using the DAT/EM MenusThere are two kinds of AutoCAD menus provided with DAT/EM CAPTURE. Instructions for configuring AutoCAD to display them appear in Chapter 3.

There is a DAT/EM pull-down menu and a set of toolbar menus:

:Most of the DAT/EM CAPTURE commands appear on the menus, as well as snap utilities and other tools. These commands are also available on the DAT/EM KEYPAD. The menus are provided as a method of quickly starting DAT/EM CAPTURE commands.

3-2 DAT/EM CAPTURE for use with AutoCAD

Day-to-Day Use of DAT/EM CAPTURE 3

Getting Started with DAT/EM CAPTURE Digitizing CommandsWhen digitizing, the user may use any of the commands that come with AutoCAD plus the specialized mapping-specific commands that come with DAT/EM CAPTURE.

For example, a building could be digitized by starting AutoCAD’s 3dpoly command and digitizing each corner of the building, then entering the letter “C” to close the polyline. The result of this time-consuming 3dpoly command will be a building with sides that are not quite perpendicular. But DAT/EM CAPTURE offers several building commands that streamline the process, allow some corners to be calculated rather than digitized, square the building sides when necessary, and automatically close the polyline.

Each of the DAT/EM CAPTURE commands is described in detail in Chapter 5. The most commonly-used DAT/EM CAPTURE commands are described below in this chapter:

• To digitize elevation contours and other point-to-point or streamed polylines, see “Digitizing Polylines with DAT/EM CAPTURE” on page 3-3.

• To digitize mapping symbols using blocks, see “Digitizing Blocks with DAT/EM CAPTURE” on page 3-4.

Digitizing Polylines with DAT/EM CAPTUREThe DAT/EM CAPTURE system uses polylines for drawing linear features. In AutoCAD, there are two types of polylines, two- and three-dimensional (2D and 3D).

Two-dimensional polylines are entities consisting of a connected sequence of line and/or arc segments. The 2D polyline takes on the elevation of the first vertex.

• Use AutoCAD’s pline or DAT/EM’s autoarc2d to digitize point-to-point 2D polylines.

• Use capt2d to digitize in stream mode, with the first vertex’s elevation rounded off to the nearest contour interval. All the other vertices will remain set to this same elevation, even if the stereoplotter elevation is changed while digitizing. This command is most useful for digitizing elevation contours. See “Capt2d” on page 5-28.

Three-dimensional polylines are entities consisting of a connected sequence of line segments. Each vertex in a 3D polyline takes on the elevation of the digitizer (stereoplotter) at the time it was digitized.

• Use AutoCAD’s 3dpoly or DAT/EM’s autoarc3d to digitize point-to-point 3D polylines.

• Use capt3d for stream mode digitizing. This command is very useful for digitizing features that vary in elevation such as streams and field boundaries. It is also used to digitize break lines for use with contour generation packages. See “Capt3d” on page 5-30.

See the following sections for more information on digitizing polylines:

DAT/EM CAPTURE for use with AutoCAD 3-3

Day-to-Day Use of DAT/EM CAPTURE3

Capt2d Stream ModeCapt2d is a command that should be used when digitizing streamed curvilinear features with fixed elevations.

• Capt2d is primarily used to digitize elevation contours

The frequency of data points captured for the polyline is a function of the curvature angle and distance criteria input in the setup dialog box. See “Setup” on page 5-112.

When using capt2d, the elevation is automatically rounded to the nearest contour interval.

For instructions on using this command, see “Capt2d” on page 5-28.

Capt3d Stream ModeCapt3d stream mode is similar to the capt2d mode, except the elevation is exact, not rounded. Each elevation value may be different along the feature. Capt3d may be used when digitizing streamed curvilinear features with varying elevations such as:

• Streams

• Fences

• Break lines for later use with contour generation packages

The frequency of data points captured for the polyline is a function of the curvature angle and distance criteria input in the setup dialog box. See “Setup” on page 5-112.

For instructions on using this command, see “Capt3d” on page 5-30.

Digitizing Blocks with DAT/EM CAPTURESymbols are defined in AutoCAD as blocks, which are a set of individual entities grouped together into a compound object. Blocks can be made to represent standard features such as utility poles, swamp symbols, runway lights, control points, and mail boxes. Typical block symbols which might be used are as follows:

The default drawing file supplied with DAT/EM CAPTURE contains a set of blocks for mapping. Each of these blocks is matched to a key on the keypad overlay or menu diagram. The blocks and overlay can be customized for any mapping purposes. For instructions on customizing the default file blocks, see “New Blocks” on page 4-1.

To place symbols with the One- or Two-Shot modes, perform the following steps:

3-4 DAT/EM CAPTURE for use with AutoCAD

Day-to-Day Use of DAT/EM CAPTURE 3

Step 1) Select a symbol key on the DAT/EM KEYPAD. DAT/EM KEYPAD keys typically set a layer, use -inssetup to set the name of the block, and activate the ins command.

Step 2) Digitize one or two points. The first point specifies the block insertion point. For the ins Rotate, ins Scale, and ins All options, the second point specifies an angle, a scale factor, or both. (One-shot blocks are placed according to the active rotation angle and map scale/symbol factor set with the setup dialog box.)

Step 3) Continue inserting blocks. The ins command remains active until another command is used.

Example: A series of power poles is to be plotted with the symbol ticks parallel to a street. The size of the UTILITYP block is correct using the setup map and scale factors.

Step 1) Select Utility Pole on the DAT/EM KEYPAD. This sets the UTILITY layer, uses -inssetup to set the block name to UTILITYP, and activates ins Rotate.

Step 2) Digitize a point at the base of a power pole.

Step 3) Move the stereoplotter parallel to the street and digitize a second point. The UTILITYP block is inserted at the digitized angle.

Step 4) Continue selecting pole bases and angles. More UTILITYP symbols are inserted.

Step 5) Select another command to cancel the symbol insertion mode.

One-Shot Mode (-Inssetup O and Ins)In One-Shot block insertion mode, the system will accept one digitized point at a time, with a beep sound each time the data switch is pressed. One-Shot is used especially for

• block placement• spot elevation placement

To activate this mode, enter -inssetup o, then set the symbol name with the ins command:

Command: -inssetupOne/Rotate/Scale/All: oCommand: insBlock name/? smalltree

Proceed to insert one or more blocks using the digitizing switch.

To set the block name and a layer for the block that is independent of the currently set AutoCAD layer, use the inssetup command instead of -inssetup. A dialog box allows all the settings to be made. However, when activating the command from the keypad, the -inssetup command should be used to avoid the dialog box.

Many of the symbol insertion keys on the keypad overlay or menu diagram activate the One-Shot mode and ins.

DAT/EM CAPTURE for use with AutoCAD 3-5

Day-to-Day Use of DAT/EM CAPTURE3

Two-Shot Mode (-Inssetup Rotate, Scale, and All)This mode is similar to One-Shot mode, but the system will accept two digitized points at a time. Two-Shot mode is used especially for:

• block placement with rotation angle specified• block placement with scale specified• block placement with both angle and scale specified

To set this mode, enter -inssetup, select Rotate, Scale, or All, then set the symbol name with the ins command. For example:

Command: -inssetupOne/Rotate/Scale/All: rCommand: insBlock name/? smalltree

Proceed to insert one or more blocks using the digitizing switch. The first digitized point will be the block insertion point, the second point will define the rotation angle, scale, or both.

To set the block name and a layer for the block that is independent of the currently set AutoCAD layer, use the inssetup command instead of -inssetup. A dialog box allows all the settings to be made. However, when activating the command from the keypad, the -inssetup command should be used to avoid the dialog box.

Some of the symbol insertion keys on the keypad overlay or menu diagram set the Two-Shot mode.

Regulating Block and Text SizeMany of the DAT/EM CAPTURE commands automatically insert blocks and text into the drawing. These commands must tell AutoCAD the block insertion size and the text size.

These routines use three variables to determine the size of text and blocks:

• Map scale

• Block scale factor

• Text scale factor

These variables appear in the DAT/EM Mapping Parameters dialog box, which may be activated with the setup command. (See “Setup” on page 5-112.)

Because the software is inserting the blocks using a scale factor, blocks should be created at a size of one ground unit in the template drawing file. (See “New Blocks” on page 4-1.)

AutoCAD Commands that are Useful for Mapping ProjectsWhile digitizing and editing a map, all of AutoCAD's commands are available. AutoCAD has many commands, some of which will never be used in mapping projects. Other commands will be used extensively.

The following is a brief list of the most commonly used AutoCAD commands for mapping projects. The user is encouraged to review them in the AutoCAD Reference Manual or the AutoCAD on-line help.

Some AutoCAD commands have a direct application to mapping projects. Read more about them in:

• “Using Layers to Separate Data” on page 3-7

• “Referencing Edge Ties” on page 3-8

• “Editing the Drawing File” on page 3-8

• “Drawing Output” on page 3-8

Using Layers to Separate DataThe concept of AutoCAD layers is similar to that of transparent overlays used in drafting applications. Within AutoCAD, any number of layers may be defined, each containing a different type of information. Colors and linetypes can be assigned to each layer.

Please read the AutoCAD online help regarding layers.

Each different type of feature in a mapping project should be digitized on a unique layer. For example, place all paved roads on the ROAD-PAVED layer, and all unpaved roads on the ROAD-UNPAVED layer. Then when it comes time to extract information about one type of feature, it is very easy to freeze all layers except the layer in question.

A default acad.dwt drawing template file is supplied with DAT/EM CAPTURE. It contains a layer scheme for mapping. This scheme may be modified to suit the project. When making a layer scheme, try to make it detailed and flexible enough that it may be used on almost any type of project. Everyone concerned, including the map compiler, the editor, and the client will appreciate a consistent layering method.

Once the layer scheme is established, the layers should be added to the keypad overlay or menu diagram. The keypad overlay or menu diagram that comes with DAT/EM CAPTURE already has the layer items matched to the DAT/EM CAPTURE acad.dwt layer definitions.

When digitizing a feature, always set the layer first by selecting the layer name on the keypad or menu.

Day-to-Day Use of DAT/EM CAPTURE3

Referencing Edge TiesWhen digitizing a model, it is useful to see what was digitized in the adjoining model, and be able to snap the new contours to the ones from the edge of the old file. Use reference files to accomplish this. Please review the xref command in AutoCAD’s online help.

Editing the Drawing FileEditing the drawing file after all features have been digitized is a very important step. The editor's task is to verify the data, join models together, break the project into map sheets, and add any additional textual or legend information.

The stereoplotter station can be used for editing if necessary; however, since compilation time and editing time often vary, and users sometimes want a more powerful computer for editing, it is more efficient to have a separate AutoCAD editing station. A commonly available tablet digitizer with a 16-button cursor is also a great editing help.

• The MAP/EDITOR, is a set of editing tools provided with DAT/EM CAPTURE.

• The autolist.arx utility speeds up getting information about objects. See page 5-20.

• The edbox command helps keep track of edited areas of a drawing. See “Edbox” on page 5-63.

All the AutoCAD commands may also be used for editing.

Drawing OutputAny ACAD drawing digitized using DAT/EM CAPTURE may be plotted like any other ACAD drawing. Refer to the AutoCAD documentation to become familiar with AutoCAD’s plotting software.

The xyzout command may be used to create ASCII files. The user is able to specify the output file format and the objects that should be exported. For instructions on exporting objects with xyzout, please see “Xyzout” on page 5-133.

DAT/EM CAPTURE’s morphexporter command may be used to write morphological data from the AutoCAD file to an INPHO .wnp file. See page 5-89.

Chapter 4. Customizing The System 4

Chapter 4. Customizing The System

The following DAT/EM CAPTURE™ software can be customized by the user:

• The template drawing with its layers and block symbols;

• The DAT/EM KEYPAD™ overlay and matching function list;

• The digitizer button definitions.

Customizing the Template Drawing The template drawing file is easily modified to contain a customized layer scheme and block symbols. When making a new default file, start with a copy of the acad.dwt file that is supplied with DAT/EM CAPTURE. This file already contains many helpful settings, and new layers and blocks may be added to it.

Note that when DAT/EM CAPTURE is installed, its acad.dwt overwrites AutoCAD’s version of acad.dwt.

A New Layer Scheme Changing the layer scheme is easy to do. First prepare a concise list of the new layers. This list should be extensive enough to be useful for any mapping project. The goal in developing a layer list is be able to use it for as many projects as possible. If the same default file is always used, both the company's employees and the clients will be able to rely on the consistent drawing format. A consistent layer scheme will also help tremendously if the files are to be translated later to another CAD system.

To input a new layer scheme, start with a copy of the acad.dwt file. Use the AutoCAD DDLMODES or LAYER commands to change and define new layers. See the AutoCAD documentation for help using these commands.

New BlocksNew blocks can be defined, or the existing ones from acad.dwt can be changed. When defining blocks, there are three very important goals:

• Make blocks the correct size, usually about 1 unit across (See page 4-2);

• Make blocks on the correct layer, usually layer 0 (See page 4-2);

• Make block components at zero elevation, Z=0.0 (See page 4-3);

• Define the new or edited block (See page 4-3).

The following sections contain some hints for creating blocks.

DAT/EM CAPTURE for use with AutoCAD 4-1

Customizing The System4

Creating a Block at the Correct SizeWhen using the DAT/EM CAPTURE symbol insertion utilities, blocks are inserted at a size determined by the current map scale and the symbol sizing factor entered in the setup dialog box. Scaling the blocks as they are inserted makes it possible to use the same block table for any scale map drawings. In other words, the same default drawing file may be used for maps drawn at 1:25, 1:500, and 1:1000.

Because the blocks are scaled at the moment they are inserted, there is one rule for block sizing:

Creating a Block on the Correct LayerA blocks retains properties of the layer on which it is inserted as well as those on which it was originally created. If the block was created on any layer other than the 0 (zero) layer, then both the layer of creation and the layer of insertion must be thawed in order to see the block.

As an example, a block called LIGHT-POLE can be created on a layer called LIGHT-POLE. If it is subsequently inserted on the UTILITY layer, then the block has properties of both the LIGHT-POLE and UTILITY layers. If the LIGHT-POLE layer was then frozen, the block would not appear on the screen. Both LIGHT-POLE and UTILITY must be thawed in order to see the block.

Because the blocks are inserted on the current layer, there is an optional rule for block layering. Please consider carefully the block’s purpose, and whether it should indeed be created on a separate layer.

The Block Size Rule:

Blocks defined in the default drawing file must be created at a size of one unit.

The exception to this is symbols that should appear oversized or undersized compared to other symbols in the file. In this case, they should be created at sizes such as 2 units or half a unit.

The Block Layer Rule (Optional):

Blocks defined in the default drawing file should be created on Layer 0.

The exception to this is blocks that should retain properties of the creation layer and the insertion layer.

4-2 DAT/EM CAPTURE for use with AutoCAD

Customizing The System 4

Creating a Block at the Correct ElevationBlocks are inserted at their creation elevation plus the current drawing elevation. To insert blocks at the stereoplotter’s exact current elevation, follow the block elevation rule:

Once the block components have been drawn, use the AutoCAD LIST command to make sure the elevation of each object is zero. If necessary, use the AutoCAD MOVE command to move an object to zero elevation.

Hint: If a block always appears at the wrong elevation, check its definition elevation by inserting the block with an asterisk (*) before the name. This inserts the symbol as individual exploded objects rather than as a block. Use AutoCAD’s LIST command to look at the elevation of each object. If necessary, move the components to zero elevation and redefine the block.

Defining a BlockUse the AutoCAD BLOCK command to define the block. Be sure the insertion point is chosen accurately. Most symbol blocks will have an insertion point exactly in the center of the symbol. Please see the AutoCAD Reference Manual for instructions on the BLOCK command.

Hint: It may be convenient to draw the blocks centered around the coordinate origin, (0,0,0). This makes it easy to define the block insertion point.

If a symbol is to be used only on a particular job, it can be generated in the individual drawing file. If it is to be added to the permanent list of symbols, then it should be created in the template drawing so that it is present every time a new file is started.

Once a new block symbol has been generated, a key for this symbol can be added to the keypad overlay or menu diagram.

Customizing the DAT/EM KEYPADPlease see the DAT/EM Keypad Operation Manual for instructions on customizing the keypad menu diagram.

Customizing the Foot Pedal and Button DefinitionsWith DAT/EM CAPTURE, the buttons and/or foot pedal(s) on the stereoplotter may be redefined. (All of the available buttons and foot pedals on the stereoplotter will be referred to collectively as “buttons.”)

To set button functions, use the buttons command or select the Edit Buttons option from the DAT/EM KEYPAD or from the Datem pull-down menu. See “Buttons” on page 5-27.

The Block Elevation Rule:

All the objects that make up the block must be at Z=0.0

The 3doffset command offers a convenient way to offset 3D polylines for mapping purposes. The resulting polyline is an even distance from the original polyline when viewed in the XY plane, and has vertex elevations similar to the ones on the original polyline. A constant elevation offset may also be specified. When using 3D polylines, it is better to use DAT/EM’s 3doffset than AutoCAD’s offset command.

To use the 3doffset command, perform the following steps:

Step 1) Before starting the command, prepare the original poly16

Step 2) line. In order to know the left and right sides of the polyline, find out which end of the polyline contains the first vertex and which contains the last.

Step 3) Start the 3doffset command:

Command: 3doffsetSelect a polyline <Last>:

Step 4) Select any polyline or accept the default to use the last digitized object.

Measure offset? No/<Yes>:

Step 5) Choose either to digitize the offset distance or to enter the distance using the keyboard:

a.) To select the offset distance with the digitizer, enter Yes. To the “Pick an offset point” prompt, carefully position the digitizer (mouse or stereoplotter) at an XYZ position that would be on the new offset polyline. That is, the digitized point should define both the side of the offset and the XY and Z distances from the original polyline. Note that this option can be accessed more quickly from the 3doffsetmeasure command. See “3doffsetmeasure” on page 5-12.

b.) To enter the offset distances using the keyboard, enter No. Three more prompts appear:

Side for new line Right/<Left>:

Select a point to the side where the new offset polyline should appear.

Enter an xy offset distance <>:

Either accept the default value or enter the distance in ground units from the original polyline to the new polyline.

Enter a z offset value <>:

Enter the elevation offset. This number is entered in ground units, and may be positive or negative. For example, if -5 is entered, each vertex on the new polyline will be set 5 units less than the elevation of the nearest point on the original polyline.

The new polyline is drawn. The number of vertices found in the original polyline is reported.

3doffsetPurpose: To offset a 3D polyline so that the polylines look equidistant in the XY plane. The new polyline may also be

offset by a constant elevation difference.

Arc3d draws a 3D polyline that alternates between point-to-point mode and arc mode. Arc3d is used primarily for close range projects. For aerial projects, use autoarc3d (page 5-17) instead:

When simulating an arc, Arc3d asks the user to choose the endpoints and the center point of the arc. Vertices, or strokes, are added to the 3D polyline to simulate an arc shape.

To use Arc3d, perform the following steps:

Step 1) Select a DAT/EM KEYPAD™ key or menu item for autoarc3d, or enter command:

Command: arc3dFrom point/Stroke:

Arc3dPurpose: To draw a 3D polyline that alternates between point-to-point mode and arc mode. The “arcs” are true 3D arcs

that are simulated by line segments. This command is useful for close range projects.

Autoarc3d draws a 3D polyline that alternates between point-to-point mode and arc mode. Autoarc3d is used primarily for digitizing roads that contain curves. For close range projects, use arc3d (See “Arc3d” on page 5-13):

Autoarc3dPurpose: To draw a 3D polyline that alternates between point-to-point mode and arc mode. The “arcs” are simulated by

line segments. The result is intended to be viewed in the XY plane. Datemsnap may be used with autoarc3d.

When simulating an arc, autoarc3d asks the user to choose the endpoints and the center point of the arc. Vertices, or strokes, are added to the 3D polyline to simulate an arc shape. These vertices vary gradually in elevation from the elevation of the first point to the middle point, and then again from the middle point to the end point.

To use autoarc3d, perform the following steps:

Step 1) (Optional) If moving the analytical or digital stereoplotter to the (X,Y,Z) of a snapped-to point is desired, turn on Datemsnap and any desired ‘osnap snaps. (See “Datemsnap” on page 5-46).

• Note that Datemsnap will override autoarc3d’s own Plotter z[OFF] 2D snap setting.

• There is a difference between Datemsnap and autoarc3d’s own Plotter z[ON] setting. Datemsnap will drive the stereoplotter to the 3D snap, but Plotter z[ON] will allow the 3D snap without moving the stereoplotter to the point.

Step 2) (Optional) Set a digitizer button to toggle the mode. Set Type=User CAD and Action=A (“A” followed by a blank space character). See “Buttons” on page 5-27 for further instructions.

Step 3) Select the keypad or menu item for autoarc3d, or type the command and choose the option:

Command: autoarc3dFrom point/Stroke/Plotter z[OFF]:

Step 4) 3D arcs are simulated using a series of straight segments, or strokes. If set small enough, the segments appear to be an arc at the plot scale. To change the number of strokes, enter S and enter a new number:

Enter number of segments in a circle for 3d arc simulation <64>:

Step 5) If snapping to other objects when Datemsnap is off, enter P to toggle the setting as follows:

• To snap to the X,Y location of the other object, but use the stereoplotter’s elevation, turn [on] the stereoplotter Z setting.

• To snap to the X,Y, and Z location of the other object, turn [off] the stereoplotter Z setting.

Step 6) For this first point, either pick a point, or enter a snapping command such as endp or ins and snap to an object. Depending on the current arc mode, the next prompt will be one of the following:

Line to point /Undo/Close/Arc/Stroke/Retro/Plotter z[OFF]:Line to point /Undo/Close/Line/Stroke/Retro/Plotter z[OFF]:

To this prompt, there are several options:

Action Autoarc3d Result

• Press the digitizing switch

• Line mode starts a straight segment. Straight segment digitizing mode remains active until either A or L is entered.

• S Enter a new number of circle segments for simulating 3D arcs.

• R Change the last two segments (three vertices) to a three-point arc.

• P Toggle the elevation setting to be used when snapping to other objects:• To snap to the X,Y location of the other object, but use the

stereoplotter’s elevation, turn [on] the stereoplotter Z setting. (Datemsnap must be off for this to work. If Datemsnap is on, the snap will always be 3D.)

• To snap to the X,Y, and Z location of the other object, turn [off] the stereoplotter Z setting. (If Datemsnap is on, the stereoplotter will also move to the snapped-to point.)

• Enter an AutoCAD snapping command such as ENDP

The BuildingFrame command creates either triangular or rectangular 3D faces inside existing closed 3D polylines (usually buildings) and extends the sides to the ground. This command may be useful to define building roof and wall planes. It is also useful for displaying shaded building structures in SUMMIT EVOLUTION’s 3D Vector Split Window.

For simplicity, all closed polylines will be called “buildings”. This is usually a closed polyline digitized along the roof of a building.

To use the BuildingFrame command, perform the following steps:

Step 1) If necessary, load the ...Program Files\AutoCAD (version)\Datem\Measure(version).arx file. To load the file, use the appload command or select Load Application from AutoCAD’s Tools menu.

Step 2) Start the BuildingFrame command and make settings.

Capt2d was designed for digitizing elevation contours, which are stream mode 2D polylines with elevations rounded off to the nearest contour interval. (If rounding is not desired, set the contour interval to zero.)

To use capt2d, use the following quick guide. Details for each step appear below.

Capt2dPurpose: To digitize elevation contours. Capt2d creates 2D polylines with elevations rounded off to the nearest contour

interval. Data capture may be toggled between stream and point-to-point digitizing.

Quick Guide to using Capt2d

1. (Optional) To perform a transparent zoom without exiting the capt2d process, activate Datpan before starting.

2. (Optional) To set a button to toggle streaming and point-to-point mode, use the buttons command and set a button to Type=UserCad and Action=s<space><space>.

3. Use setup to set the contour interval for elevation rounding. If rounding is not desired, set the contour interval to 0.0 (zero).

4. Select capt2d on the keypad menu or type capt2d.

5. Start drawing the polyline. Press the digitizing switch to activate the stereoplotter’s pen-down status. Begin tracing the polyline.

6. If desired, enter U to undo the last vertex, C to close the polyline, S to toggle to point-to-point digitizing mode, or enter transparent AutoCAD snaps such as ’osnap after activating point-to-point digitizing mode.

7. End the polyline. Press the <Enter> switch to set the pen-up status.

To start capt2d, select a layer for the polyline, then select capt2d from the keypad or enter capt2d,

Command: capt2dPolyline from point/(S)treaming [ON]:

The rounded elevation (the elevation that will be assigned to the polyline) will be displayed at the lower left corner of the AutoCAD screen next to the (X,Y, true Z) coordinate display. This rounded elevation will only be displayed when capt2d is active.

After the first few points have been digitized, more options appear in the prompt:

Polyline to point/Undo/Close/(S)treaming [ON]:

Input options for capt2d are as follows:

• Digitize a stream of vertices as the cursor moves: Entering S toggles the stream and point-to-point modes. If the prompt indicates streaming is on, activate the stereoplotter’s “pen down” status and move the cursor to start stream digitizing. On most stereoplotters, press the digitizing switch one time to activate the “pen down” stream mode. On other stereoplotters, hold down the digitizing switch. Vertices are collected automatically as the cursor moves.

• Digitize individual vertices using point-to-point mode: Entering S toggles the stream and point-to-point modes. If the prompt indicates streaming is off, press the digitizing switch to add one vertex to the polyline.

• Toggle stream and point-to-point digitizing: The data capture mode may be toggled between stream and point-to-point digitizing by entering S<space><space>. The prompt indicates whether streaming is on or off.

• Undo: Enter U to remove the last vertex without ending the polyline. This option may be used repeatedly to remove all but the first vertex.

• Close and end the polyline: Enter C to close and end the polyline.

• Snap to other objects: First activate point-to-point digitizing mode by entering S to toggle to the point-to-point digitizing mode. Enter transparent AutoCAD snap commands such as ‘osnap and snap to other objects.

• End the polyline: To end the polyline without closing, press the switch programmed for a space, “ ”. (See “Buttons” on page 5-27.)

The density of vertex capture during stream digitizing is regulated by the “collecting data” variables curvature angle and XY distance entered in the setup dialog box. (See “Setup” on page 5-112.)

Since the DAT/EM MAP/EDITOR filter routine can be used to remove excess points from polylines, it is best to set the spline filtering parameters to sample just a few too many points. The vertices left after filtering are all in their original locations, so filtering a concentrated polyline is usually better than having to curve fit a sparse polyline to fill in missing data.

On most stereoplotters, press the digitizing switch one time to activate the “pen down” stream mode. On other stereoplotters, hold down the digitizing switch. Vertices are collected automatically as the cursor moves.

• Digitize one vertex using point-to-point mode: If the prompt indicates streaming is off, press the digitizing switch to add one vertex to the polyline.

• Toggle stream and point-to-point digitizing: The data capture mode may be toggled between stream and point-to-point digitizing by entering S<space><space>. The prompt indicates whether streaming is on or off.

• Toggle the use of the stereoplotter’s Z for snapping: If snapping to X, Y, and Z of another object, set Plotter z to OFF. If snapping to only the X and Y location of another object, set Plotter z to ON. To toggle the setting, enter P.

• Undo: Enter U to remove the last vertex without ending the polyline. This option may be used repeatedly to remove all but the first vertex.

• Snap to other objects: Enter transparent AutoCAD snap commands such as ‘osnap or endp and snap to other objects. Use this option while in point-to-point digitizing mode. If Datemsnap is on, the stereoplotter will drive to the (X,Y,Z) location of the snapped-to point. See “Datemsnap” on page 5-46.

• Close and end the polyline: Enter C to close and end the polyline.

• End the polyline: To end the polyline without closing, press the switch programmed for a space, “ ”. (See “Buttons” on page 5-27.)

The density of vertex capture during stream digitizing is regulated by the “collecting data” variables curvature angle, XY distance, and Z distance entered in the setup dialog box. (See “Setup” on page 5-112.)

The primary distance filter for capt3d is the XY distance. The Z distance is used for special Digital Terrain Model (DTM) work, where a 3D Polyline point should be sampled if the elevation changes. Often, the Z distance is set quite high to disable it from influencing the sampling of normal contouring work. In a similar manner, when doing DTM projects, set the XY distance quite high to disable it, set the Curvature angle to zero, and then sample only on the basis of elevation change using the Z distance filter.

Since the DAT/EM MAP/EDITOR filter routine can be used to remove excess points from polylines, it is best to set the spline filtering parameters to sample just a few too many points. The vertices left after filtering are all in their original locations, so filtering a concentrated polyline is usually better than having to curve fit a sparse polyline to fill in missing data.

The changescale command multiplies every coordinate contained in every object of the file by a conversion factor. For mapping purposes, this effectively changes the ground units of the drawing. Units available for conversion are meters, centimeters, millimeters, inches, feet, and furlongs.

Changescale should be generally considered an editing tool. If it is used during map compilation, then a new orientation must be performed using the new ground units.

To change the units of the drawing, use the changescale command:

Command: changescale

A dialog box appears asking for the desired units:

When OK is selected, the conversion factor will be multiplied times every coordinate contained in every object in the file.

Rescaling to or from English and Metric units will leave elevation contours with decimal elevations. For example, when changing from feet to meters, the 100 ft, 125 ft, and 150 ft contours will obtain elevations of 30.48 m, 38.10 m, and 45.72 m. It is recommended that elevation contours be regenerated with the new ground units when necessary.

In aerial photogrammetry, the most common AutoCAD viewpoint is (0,0,1), so that the user looks at the X,Y plane and uses Z for elevation. In close-range photogrammetry, the Y and Z axis are often swapped to give (0,1,0) as the view; Y is used for “depth” changes, and the user looks at the X,Z plane.

Closergview, or “Close Range View” is used to quickly toggle the viewpoint between (0,0,1) and (0,1,0). To change the view, select the keypad or menu item, or enter the command:

Command: closergview<Aerial view>/Close range view:

Enter A for a viewpoint of (0,0,1). Enter C for the close-range viewpoint of (0,1,0). The command uses AutoCAD’s dview twist to change the viewpoint.

ClosergviewPurpose: To change the AutoCAD view to (0,1,0) for a close-range project or to (0,0,1) for an aerial project.

The datemrotate command activates AutoCAD's dview twist command, and rotates the view to match the stereoplotter model. It is especially helpful when North on the stereo model is not aligned along the stereoplotter's y direction.

For example, if north is to the right on the photos, then when the stereoplotter moves to the right, the cursor on the screen moves up. This is very distracting to the user. datemrotate is used so the direction of the cursor movement is the same as the stereoplotter movement.

Pick datemrotate on the keypad or user menu, or type in the datemrotate command:

Command: datemrotatePick a point: (digitize a point with the stereoplotter)Move straight up on the stereoplotter and pick a point.(in the direction of Y axis): (move up and digitize again)

Almost any point may be picked. Just make sure there is room to move up in the stereoplotter's Y direction to take the second point:

Move straight up in Y on the stereoplotter and digitize a point.

DTMit manages inclusion and exclusion areas, grid placement and view, objects for placement, and movement options. It is the most useful on stereoplotters that have computer-driven move capabilities, such as SUMMIT EVOLUTION and most analytical stereoplotters.

DTM digitizing on analog stereoplotter is often considered too complicated and time consuming, because the user must perform all of the XY stereoplotter movement manually. However, if an analog stereoplotter is the only choice available, some of the movement options may be simulated with a mechanical axis-locking bar. Follow the manufacturer’s directions for using such a device. DTM digitizing is easier on an analog stereoplotter that has SUPER/IMPOSITION, because the user can see the grid point markers without looking away from the images.

To use DTMit, perform the following steps:

Step 1) (Optional) If using the SUMMIT EVOLUTION stereoplotter, the Terrain Following tool may be used at the same time as DTMit. This is how it works: The stereoplotter moves to the XY of the DTM node, Terrain Following places the Z at the interpolated elevation, then the operator further adjusts the Z to be exactly on the ground; as long as the operator does not move XY, Terrain Following will not interfere with the operator’s Z adjustment. If Terrain Following is to be used, activate it, then lock the XY cursor movement by selecting X and Y from SUMMIT’s XYZ Movement toolbar:

DTMitPurpose: To set up a Digital Terrain Modeling (DTM) project and digitize XYZ data on a grid.

• Points may be digitized on the grid point, offset from the grid point, or points may be skipped.

• Digitizing may begin anywhere on the grid.Sample DTMit project

If the toolbar does not appear in SUMMIT EVOLUTION, select Toolbars from SUMMIT’s View pull-down menu. Check on the XYZ Movement toolbar.

Use the XYZ Movement toolbar to lock the X and Y cursor movement.

Step 2) Digitize new inclusion and exclusion areas or verify that they already exist:

a.) Although 2D polylines will work, it is recommended to draw all inclusion and exclusion boundaries using 3D polylines at the ground elevation. The 3D polylines are especially important if using SUPER/IMPOSITION, so that the boundaries and grid markers are visible at ground elevation.

b.) The grid marker elevations are calculated based on the elevation of the inclusion and exclusion boundaries. Be aware that most stereoplotters will drive to the XYZ of the first grid marker, so do not draw the boundaries at Z=0 unless the project is near sea level!

c.) Inclusion and exclusion boundaries may be drawn either clockwise or counterclockwise.

d.) Inclusion and exclusion boundaries may either be placed on separate layers or selected individually. It is the user’s choice whether to use separate layers, or even many different layers, for inclusion and exclusion areas polylines.

Step 4) Select the Settings tab and begin to make selections:

Step 5) Continue to make selections from the Settings tab:

Settings tab Enter the desired Grid Angle. To align the grid to the stereoplotter model’s angle, click the Model’s Kappa button.

Set the Size to the XY distance between grid points.

To show grid point markers, check Show Grid and choose a layer for the markers.• The grid markers are a visual

aid to make sure the grid has been calculated correctly.

• The grid markers are POINT objects. They are inserted into the file every time Collect is selected with Show Grid checked on.

• Some users find the grid markers to be distracting in the SUPER/IMPOSITION view. If this is the case, either don’t place the markers, or freeze the grid marker layer later.

To erase all pre-existing POINT objects on the selected Show Grid layer, click the Erase all points... button.• All POINTs found on that

layer in the entire file are erased immediately.

• Although the erase has been done, it is not visible until the dialog box closes.

• If this button is used in error, close the dialog and use AutoCAD’s Undo.

Choose whether to use POINTs or BLOCKs for the digitized XYZ data. Set the Block name, block Scale and the Output Layer. The block and layer must already exist in the drawing.

Choose a movement option:• Free Movement allows the stereoplotter to move in any

direction away from the current grid point. XYZ data may be digitized anywhere. Analog stereoplotters should use this option.

• Lock to Line allows movement only along the current line (row) of grid points. XYZ data may be digitized anywhere along the line. This option does not apply to analog stereoplotters.

• Lock to Point freezes the stereoplotter at the current grid point. XYZ data may only be digitized (or skipped) at exact grid points. This option does not apply to analog stereoplotters.

Drive to Ground is available for SUMMIT EVOLUTION stereoplotters. As the stereoplotter moves to the grid point location, image matching is performed to try to set the elevation to the ground. This behaves as if SUMMIT EVOLUTION’s Align button had been selected immediately after each move to a grid point. The usefulness of this option depends on how easily automatic elevation matching is done on the current images. It is easy to toggle this option on and off if elevation matching fails in certain areas on the images.

Step 6) Continue to make selections from the Settings tab:

Step 7) Now choose the Select tab and select the inclusion and exclusion polylines or layers:

Choose a grid row movement setting:

• indicates that it is already set to move left to right along one grid row, then right to left along the next grid row.

• indicates that it is already set to move in the same direction along every grid row.

For systems with Super/Imposition, choose a setting for Indicate the DTM position in SI:• If the icon is light gray (on), then a temporary superimposed

point marker appears to mark the current grid XY position. The Z of this point is set to the Z of the most recently digitized point. Read more about managing the SUPER/IMPOSITION display of DTM points below in Step 12.

• If the icon is dark gray (off), then no additional point marker is displayed at the current grid point position.

Select tabThere are two methods to specify the Include areas. They are both used at the same time during grid calculations:• To select individual polylines on any layer, select Objects

and then click on the Begin selecting objects/layers button. Select every polyline to be used as an inclusion boundary, then press the <Enter> key to return to the dialog.

• To select all objects on certain layers, select Layers. Then there are two choices for obtaining the layer names:

a.) Select the layer from the pop-down list, then click the “+” icon.

b.) Click on the Begin selecting objects/layers button. Select a polyline from each layer to be used as an inclusion boundary, then press the <Enter> key when finished. The layer names are taken from the polylines and added to the list.

Note that all objects and layers are used during grid calculation, regardless of the radio button status. This allows you to select by layer and by object for the same run.

To select the Exclude areas, follow the directions for the Include areas, but select exclusion polylines or exclusion layers.

Step 8) Now choose a grid collection start option:

Step 9) If Collect At was selected, a prompt appears:

Select the area to begin collecting {pick}

With either the mouse or the stereoplotter, select near the grid point or area where digitizing should begin. The stereoplotter drives to the grid point that is nearest to the selected point, and the data collection mode begins.

Step 10) If the grid point markers were checked on, the grid appears as points in the drawing. Verify that the grid has been calculated in the correct XY locations. Remember, the grid point markers are not at the ground Z. They are not data points, they are a tool for viewing the calculated grid.

Step 11) A prompt appears:

Measure point (Cancel to skip/Return to dialog/Toggle DTG(now off)/Undo):

Collect XYZ data. Choose from the following actions:

a.) Digitize a point: Carefully position the stereoplotter at the Z elevation of the ground. Or, if XY movement is possible, carefully position the stereoplotter at the desired XYZ coordinate. Press the stereoplotter’s “Pick” digitizing switch1.

b.) Skip a point: Press the stereoplotter’s “Cancel” switch to skip to the next grid point.

c.) Stop digitizing and return to the dialog: Enter R to stop digitizing and return to the dialog. Changes may then be made to the DTMit settings, or the DTMit dialog may be closed. To resume the same project later, use the same DTMit settings; previously digitized points will be found and skipped automatically.

d.) Toggle “DTG” (Drive to Ground): Enter T to toggle “Drive to Ground” on or off.

e.) Undo the last point: Enter U to remove the last point and move back to its location. The points can be undone back to the first point of this DTMit session. If part of the project was digitized with a previous run of DTMit, those previously existing points cannot be undone.

1. In DTM projects, the “Pick” and “Cancel” switches are used repeatedly. For the user’s comfort, the most easy-to-use switches should be programmed to these functions. See “Buttons” on page 5-27 for instructions.

Choose a grid collection start option:• Choose Collect to drive the stereoplotter to the

first point on the grid and begin XYZ data collection mode.

• Choose Collect At and to drive the stereoplotter to a selected starting point. To the “Select the area to begin collecting” prompt, digitize a point near the desired grid point. The stereoplotter drives to the grid point that is nearest to the selected point, and the data collection mode begins.

Step 12) If SUPER/IMPOSITION is present, make sure the settings are convenient for the user. The following are hints and troubleshooting ideas for DTMit with SUPER/IMPOSITION:

a.) While the Show Grid markers are convenient for checking the grid calculation, they may be distracting during digitizing. Use the transparent ‘layer command to freeze the grid marker layer without interrupting DTMit.

b.) If using SUMMIT EVOLUTION, try different SUPER/IMPOSITION Clip Scope settings. Some users may like the way Clip Scope makes the marker disappear when the cursor is very close to it.

c.) If grid markers do not appear on the SUPER/IMPOSITION display, check that SI is turned ON in AutoCAD and that POINT display is on in the SUPER/IMPOSITION client or in SUMMIT EVOLUTION’s SI settings. SUMMIT EVOLUTION users should check the Clip Scope setting.

d.) If two different grid markers appear at the current grid location, it is because Show grid and Indicate the grid location in SI are both on. They appear at different elevations because the Show grid point is based on the inclusion/exclusion area elevations, and the Indicate... point is based on the elevation of the last digitized point. To reduce the number of points displayed in SUPER/IMPOSITION, simply freeze the Show grid layer using the transparent ‘layer command.

The edbox command is a tool to keep track of edited areas on a drawing. Edit boxes are useful to avoid gaps in the edited area, and they make it easier for two people to edit the same project.

Use edbox to place box-shaped blocks over a newly digitized drawing. Completely edit the area under a box, then erase the box. When the boxes are all gone, the project is completely edited.

First start the command and define the entire area of box coverage:

Command: edboxBox from point:Box to point:

Select opposite corners of the area to be covered. Then define the box block size:

Block size from point:Block size to point:

Select opposite corners defining the size of an individual box. The box size should be defined so all objects in the box can be edited without zooming smaller than the box.

Step 2) Select an editing mode and follow the prompts:

a.) End: To replace an end section of a polyline with a new section, enter E, e, or end.

Select polyline break point:

Select the point on the polyline where the new section is to connect. The closest end section is removed and a drawing prompt appears. Go on to the next step for information about drawing the new section.

b.) Inner: To replace an interior section of one polyline with a new section, enter I, i, or inner.

Select first break point: Select second break point:

Select the ends of the polyline section that is to be replaced. The section that will be removed is highlighted in red and a digitizing prompt appears. Go on to the next step for information about drawing the new section.

c.) Join: To replace the end sections of two polylines, draw a new section, and join all three parts together into one polyline, enter J, j, or join.

Select first polyline break point:Select second polyline break point:

Select the points on the first and second polylines where the new section is to connect. The polylines may be 2D or 3D. Note that if one polyline is 3D, the result is 3D. If both polylines are 2D, the result is 2D.

Now choose the correct ends to remove. The first polyline turns green on the end that is to be saved and red on the end that is to be removed. A prompt appears:

Accept/Opposite breakpoints? <A>

If the red end is the correct end to remove, select A or <Enter>. To remove the green end instead, enter O, o, or Opposite; the red highlight changes to indicate the other end of the polyline. Repeat for the second polyline.

The red highlights remain on the screen to show the end sections that are to be removed. A digitizing prompt appears. Go on to the next step for information about drawing the new section.

d.) ShiftZ: To edit the elevation of individual vertices, enter S, s, or shiftz.

Please measure vertex(3d) or line(2d)at its new elevation:

If using the stereoplotter to digitize, set the stereoplotter to the correct elevation, then pick a 3D polyline’s vertex or a 2D polyline entity with the stereoplotter’s digitizing switch. If using the system mouse to digitize, first use AutoCAD’s elev command to set the correct elevation, then use editline ShiftZ and pick with the mouse. Repeat as necessary for other vertices. Enter <Esc> to exit the ShiftZ prompt and return to the other editline options.

Step 3) Digitize the new section. The digitizing prompt is different depending on whether the original polyline is 2D or 3D. The combined 2D and 3D choices are as follows:

Step 4) Input <Enter> to finish the new section and end the editline command.

Action Editline Result

• Digitize a point Digitize a segment endpoint or an arc point, depending on which digitizing mode is active.

• Enter an AutoCAD snapping command such as ENDP

Snap to another object and continue.

• <Enter> or spacebar Finish the new polyline section and complete editline.

• 3 For 2D polylines only. Change from straight segment digitizing mode to 3-point arc mode. Digitize a point along the arc, then digitize the end point of the arc.

• A Change from straight segment digitizing mode to arc mode.

• For a 3D polyline: Start a 3-point simulated arc. Digitize a point along the arc and digitize the arc’s end point. Because true 3D arcs are not possible in AutoCAD, many straight line segment strokes are added to simulate an arc shape. These vertices vary gradually in elevation from the elevation of the first point to the middle point, and then again from the middle point to the end point.

• For a 2D polyline: Start a 2-point arc. Digitize the end point of the arc.

• C Close the polyline and finish the editline command.

• L Change from arc mode to straight segment digitizing mode. Digitize a segment endpoint.

• P Use this option only when DAT/EM CAPTURE is running and the stereoplotter is used as the digitizer. Toggle the elevation setting to be used when snapping to other objects:

• To snap to the X,Y location of the other object, but use the stereoplotter’s elevation, turn [on] the stereoplotter Z setting.

• To snap to the X,Y, and Z location of the other object, turn [off] the stereoplotter Z setting.

• R Change the last two straight segments (three vertices) to a three-point arc. This is a simulated arc for 3D polylines.

• S Enter a new number of circle segments (strokes) for simulating 3D arcs. A higher number produces more segments.

• U Remove the last vertex and continue.

Ins is a function that offers quick and repeated block or point insertion. This command is often called along with -inssetup from the .kds keypad overlay or menu diagram definition file in the symbol insertion section. For example, to insert a series of runway light blocks at a selected scale, a keypad key is programmed as follows:

-LAYER{RET}SET{RET}UTILITIES{RET}-INSSETUP{RET}S{RET}INS{RET}RLIGHT{RET}

To use the ins command, perform the following steps:

Step 1) Make settings using the inssetup or -inssetup command. See “Inssetup and -Inssetup” on page 5-73.

Step 2) If inserting a block that has block tag attributes in its definition, use the setup command to choose a setting for the Prompt for block tag information. If this setting is checked on, then ins prompts for block tags. See “Setup” on page 5-112.

Step 3) Start the ins command:

Command: ins

Step 4) To the “Block name” prompt, enter the block name if necessary. The block name will appear automatically if it was set with the inssetup dialog box. Note that this prompt does not appear if placing points.

Block name (NAME)/?: (enter the block name if necessary)

Step 5) To the “Undo/Pick point” prompt, digitize the insertion location for the block or point.

Undo/Pick point: (digitize the insertion location)

Step 6) If the “Scale”, “Rotate”, or “Scale and Rotate” prompt appears, digitize a second point to define the scale and/or rotation angle for the block. Note that this prompt may not appear for some settings.

Scale and Rotate: (digitize the scale/rotation)

Step 7) Whenever necessary, enter U to undo (remove) the last inserted block or point.

Step 8) If desired, repeat steps 5, 6, and 7 to insert more blocks or points.

Note that the shot command is still available to insert blocks, but ins now has all the functionality of shot (see “Shot” on page 5-116.). Additionally, inssetup and ins can insert blocks on a specified non-current layer.

This ins and inssetup/-inssetup commands work together to make block or point insertion settings, then quickly and repeatedly insert blocks or points. Inssetup activates a dialog box to make settings for the ins command. -Inssetup works on the command line and does not activate a dialog box. Inssetup offers one layer setting that -inssetup does not, but most of the settings for ins can be made interchangeably by either inssetup or -inssetup.

To use the -inssetup command to make command line settings for ins, perform the following steps:

Step 1) Start the -inssetup command:

Command: -inssetupOne/Rotate/Scale/(A)ll/Point:

Step 2) Enter the desired letter option to make settings for the ins command:

a.) Enter the letter O to insert a block each time the digitizing switch is pressed.

b.) Enter R to insert a block after pressing the digitizing switch twice. The first pick is the insertion point, and the second pick defines the block rotation angle.

c.) Enter S to insert a block after pressing the digitizing switch twice. The first pick is the insertion point, and the second pick defines the block scale factor.

d.) Enter A to insert a block after pressing the digitizing switch twice. The first pick is the insertion point, and the second pick defines both the rotation angle and the block scale factor.

e.) Enter P to insert an AutoCAD POINT each time the digitizing switch is pressed.

Step 3) Use the ins command to insert blocks or points at any time after -inssetup is finished. Note that any settings made later with the inssetup dialog box override settings made previously with -inssetup.

Because -inssetup does not activate a dialog box, the -inssetup and ins commands are often programmed together on the DATEM KEYPAD. For example, to insert a series of runway light blocks at a selected angle, a keypad key is programmed as follows:

-LAYER{RET}SET{RET}UTILITIES{RET}-INSSETUP{RET}R{RET}INS{RET}RLIGHT{RET}

• If Rotate and/or Scale are checked, an additional point must be digitized to define the rotation and/or scale.

• If they are not checked, each single digitized point insert the block at the currently set scale and rotation.

• If Block is selected, the ins command prompts for a block name and then inserts that block. If the block definition includes a block tag and Prompt for block tag information is checked on in setup, then it will also prompt for the block tag.

• If Point is selected, the ins command inserts an AutoCAD POINT each time the digitizer switch is pressed.

If Force Layer is on, then the block or points is inserted on the selected Layer. The current AutoCAD layer will not be changed.

The interp command is used to add intermediate elevation contours to digital topographic maps. Index contours must already be present in order for the command to run. For example, the following diagrams show the contours before and after intermediate contour interpolation:

When to Use InterpolationWhen used wisely, interp can save time without compromising the accuracy of the digital map information. It is important to know when to use interp, and when not to use it.

Use interp when the elevation change is a fairly steady gradient, whether steep or flat. If the index contours are generally an even distance apart, then interp can be used accurately and successfully.

Do not use interp if the ground is bumpy and uneven. The program will always attempt to place the intermediate contours evenly between the index contours. In the case of bumpy ground features, this may not accurately represent the ground. For example, the program will use the following index contours to produce these results:

InterpPurpose: To interpolate intermediate elevation contours.

Warning!

Do not use interpif the ground is bumpy and uneven!

However, the true ground contours might not be evenly spaced. The following examples show other possible intermediate contours for these index contours:

In these examples, the elevation is truly ambiguous, and should not be estimated by any sort of interpolation program.

Draw a Boundary for Interp (Optional)Using a boundary is optional with the interp command. When a boundary is used, contours are interpolated only within the boundary polyline. Draw a boundary by digitizing a polyline around the area of index contours to be used for intermediate contour interpolation:

Boundary and Contour Polyline Information:

• Number of Vertices:

Upper Limit: The total number of vertices contained in the boundary line plus all the vertices in the index contours inside the boundary cannot exceed 14,000. An error message will be displayed if there are too many vertices. If this limit is too low, please contact DAT/EM Systems for an expanded version.Lower Limit: Each contour polyline must have more than three vertices.

Ground elevations are irregular

Contours would be interpolatedevenly, and may not be correct.

These ground featurescould not be interpolated.

• Number of Index Contours: There must be at least two index contours; however, there is no upper limit to the number of index contours inside the boundary. The only limit is the total number of vertices as described above.

• Boundary Assumed Closed: The boundary is assumed closed. That is, if the boundary's first and last vertices are not snapped to each other, then the interpolation utility will assume there is a line between the first and last vertices of the boundary.

• Index Contour Elevations: The index contour lines must already be at the correct elevations. The interpolation utility uses the index contour elevations to determine the placement elevation of the new intermediate contours.

• Boundary Elevation: The boundary can be placed at any elevation.

• Index Contours Inside or Extending Beyond the Boundary: The index contours may be completely inside the boundary, begin or end at the boundary, or extend beyond the boundary.

The following is a sample boundary. Notice it is not a simple rectangle. This boundary excludes areas where the elevation should not be represented by evenly spaced intermediate contours:

In psqr and psqr3d, the sides of each building are squared to the first segment drawn on that building. With the “orthogonal” squaring function opsqr2d, all buildings are squared to a pre-defined base angle. Opsqr2d is useful when many buildings are aligned with each other or with a street.

The psqr command uses a 2D polyline. Each vertex has the same elevation as the first point. To use a 3D polyline, see Opsqr3d and Psqr3d.

To use opsqr2d, perform the following steps:

Step 1) Use the Setup command to make building squaring selections. set the Building squaring tolerance and Automatically Close settings. For more information about Setup, see page 5-112. For information about the Building squaring tolerance, see “Notes About the Squaring Angle for Psqr, Psqr3d, Opsqr2d, Opsqr3d” on page 5-102.

Step 2) Start the command:

In psqr and psqr3d, the sides of each building are squared to the first segment drawn on that building. With the “orthogonal” squaring function opsqr3d, all buildings are squared to pre-defined base angle. Opsqr3d is useful when many buildings are aligned with each other or with a street.

The digitizing prompts for opsqr3d are exactly the same as for opsqr2d and psqr. There are two differences between the commands:

• Opsqr3d uses a 3D polyline instead of a 2D polyline. Each building vertex obtains the digitizer elevation at the time it was digitized.

• The Z tolerance and Pitched settings entered in the Setup box apply to opsqr3d and psqr3d. They enable vertical segments between rooflines that drop to different elevation levels.

To use opsqr3d, perform the following steps:

Step 1) Use the Setup command to make building squaring selections. set the Building squaring tolerance, Z tolerance, Pitched or Flat, and Automatically Close settings. For more information about Setup, see page 5-112. For information about the Building squaring tolerance, see “Notes About the Squaring Angle for Psqr, Psqr3d, Opsqr2d, Opsqr3d” on page 5-102.

Step 2) Start the command:

Command: opsqr3dBase angle (default) degrees -90..90/(P)ick /<Enter>:

The Base angle setting will be used to align the buildings. To accept the default, press <Enter>. To change it, either enter the angle on the keyboard, or enter P and pick two points to define the angle.

Step 3) To the “Square From point/Xy tol/Z tol/Plotter z[ON]: ” prompt, make new settings if desired:

a.) To change the tolerance angles, enter X or Z and the new values.

b.) To use the stereoplotter’s current Z setting for each vertex, make sure Plotter z is ON. To toggle the Plotter z setting, enter P.

c.) Press <Enter> to return to digitizing.

Note: To override the Automatically Close off setting, enter a C to fill in two missing sides and close.

b.) For buildings with more than four segments, digitize each corner. Press <Enter> to fill in the one missing side if Automatically Close is set on (see Step 1). If Automatically Close is set off, the polyline simply ends.

c.) If digitizing elevation drops (such as where one roof surface drops down to a lower roof surface), the Pitched setting must be on. Digitize the last corner of one roof, then change the elevation to the new roof level and digitize the point. If the angle to the Z axis has not exceeded the Z tolerance, then opsqr3d forces the segment between the two rooflines to be vertical. That is, the X,Y remains the same as the point on the first roof level, but the Z to set to the elevation of the second roof level.

d.) After the first three corners have been digitized, U may be entered to undo the last digitized corner. Every corner may be removed except the first two corners. Resume digitizing at any time.

The orient command is used automatically when the DATEM CAPTURE application is first loaded, but if necessary, it may be used at any other time to reestablish communication to AutoCAD. The orient command is very similar to resetting the digitizer using AutoCAD’s reinit command, except that it also sends the orientation information to the AutoCAD tablet. As it finishes, it runs Datemrotate so that north appears straight up on the AutoCAD view.

The orient_only command is similar to orient, but it does not run Datemrotate.

The orient or orient_only command may be helpful after communication between AutoCAD and DATEM CAPTURE is lost. That is, if moving the stereoplotter no longer moves the cursor or updates the coordinates in AutoCAD, then try the orient or orient_only command.

When the orient command is entered, messages appear in the AutoCAD text window. These message may seem familiar, because they are the same messages that were seen when the DATEM CAPTURE application was loaded.

Command: orientCalibrating tablet...Adjusting for Kappa...Regenerating model.

Because orient_only does not run Datemrotate, its messages show only the tablet calibration:

Command: orientCalibrating tablet...

If the communication was successfully reestablished, the stereoplotter should be in control of the cursor movement in AutoCAD. If desired, visit a control point to make sure the location matches the correct coordinates.

Step 1) Select whether or not to have the polyline close as the command finishes. Use the Setup command and set Automatically Close on or off. For more information about Setup, see page 5-112.

Step 2) Start psqr. Press a keypad or menu key, or type

Command: psqr

Step 3) Digitize the two corners by the longest side of the building. Choosing the longest side first helps to more accurately define the base angle of the building. Then digitize successive corners as follows:

a.) For rectangular buildings, digitize only the first three corners. Press <Enter> (on the keyboard or a programmed switch). It will fill in the two missing sides if Automatically Close is set on (see Step 1), but it will fill in one missing side if Automatically Close is set off. Note: To override the Automatically Close off setting, enter a C to fill in two missing sides and close.

b.) For buildings with more than four segments, digitize each corner. Press <Enter> to fill in the one missing side if Automatically Close is set on (see Step 1). If Automatically Close is set off, the polyline simply ends. Note: To override the Automatically Close off setting, enter a C to force the polyline to close.

c.) After the first three corners have been digitized, U may be entered to undo the last digitized corner. Every corner may be removed except the first two corners. Resume digitizing at any time.

Step 4) If desired, continue digitizing more buildings.

Step 5) To completely end the command, press <Enter> a second time.

PsqrPurpose: To digitize and perform squaring on buildings and other man-made objects that have sides at right angles to

each other. Psqr uses 2D polylines.

Notes About the Squaring Angle for Psqr, Psqr3d, Opsqr2d, Opsqr3dPsqr squares building sides according to the currently set building squaring angle. The tolerance is entered in the setup dialog box (see “Setup” on page 5-112).

The building squaring angle units are in decimal degrees. During building squaring, if a building side is less than the tolerance angle from square with respect to the previous side, then it is adjusted to be perpendicular to the previous side. The tolerance should be set so the majority of buildings will be squared nicely, while unusually shaped buildings retain their actual angles. The best tolerance for the drawing may depend on the map scale.

The following diagrams show how the squaring angle works:

Points picked for the first four building corners (incomplete building)

The prompts for psqr3d are exactly the same as for psqr. There are two differences between the commands:

• Psqr3d uses a 3D polyline instead of a 2D polyline. Each building vertex obtains the digitizer elevation at the time it was digitized.

• The Z tolerance and Pitched settings entered in the Setup box apply to opsqr3d and psqr3d. They enable vertical segments between rooflines that drop to different elevation levels.

To use psqr3d, perform the following steps:

Step 1) Use the Setup command to make building squaring selections. set the Building squaring tolerance, Z tolerance, Pitched or Flat, and Automatically Close settings. For more information about Setup, see page 5-112. For information about the Building squaring tolerance, see “Notes About the Squaring Angle for Psqr, Psqr3d, Opsqr2d, Opsqr3d” on page 5-102.

Step 2) Start the command:

Command: psqr3d

Step 3) Digitize the two corners by the longest side of the building. Choosing the longest side first helps to more accurately define the base angle of the building. Then digitize successive corners as follows:

a.) For rectangular buildings, digitize only the first three corners. Press <Enter> (on the keyboard or a programmed switch). It will fill in the two missing sides if Automatically Close is set on (see Step 1), but it will fill in one missing side if Automatically Close is set off. Note: To override the Automatically Close off setting, enter a C to fill in two missing sides and close.

b.) For buildings with more than four segments, digitize each corner. Press <Enter> to fill in the one missing side if Automatically Close is set on (see Step 1). If Automatically Close is set off, the polyline simply ends. Note: To override the Automatically Close off setting, enter a C to force the polyline to close.

c.) If digitizing elevation drops (such as where one roof surface drops down to a lower roof surface), the Pitched setting must be on. Digitize the last corner of one roof, then change the elevation to the new roof level and digitize the point. If the angle to the Z axis has not exceeded the Z tolerance, then opsqr3d forces the segment between the two rooflines to be vertical. That is, the X,Y remains the same as the point on the first roof level, but the Z to set to the elevation of the second roof level.

d.) After the first three corners have been digitized, U may be entered to undo the last digitized corner. Every corner may be removed except the first two corners. Resume digitizing at any time.

Step 4) If desired, continue digitizing more buildings.

Building squaring, max(degrees)

This is the limit for the angle in the X,Y plane for the psqr, psqr3d, opsqr2d, opsqr3d commands. The units are in decimal degrees. For details, see “Psqr” on page 5-101.

Z Tolerance, max(degrees)

This is the angle in the X,Z plane for the psqr3d and opsqr3d commands. It allows two roof levels to be connected by a vertical segment. If two points are digitized and their angle to the Z axis does not exceed the Z tolerance, then the points are connected by a vertical segment. The units are in decimal degrees.

Pitched or Flat If pitched is on, psqr3d and opsqr3d will allow a vertical closing segment to be added between two roof levels. If flat is on, the closing segment will be between the last digitized point and the first point, and may have different X,Y, and Z values on each end (not necessarily vertical).

Automatically Close

If Automatically Close is on, then the psqr, psqr3d, opsqr2d, opsqr3d commands will add a closing segment when they are finished. If this setting is off, the polyline remains open. The “open” option may be useful for digitizing man-made objects that have square corners, but that are not buildings.

Step 5) Select OK to run the command and import the objects.

Enter the input file name or select Browse to help locate the file.

If desired, use Load to retrieve previously saved settings

Select the object types to be inserted. The settings needed depend on the Line Format choices.• The Type Identifier field is only active when Object

type is placed in Selected Fields below. Enter the exact object identification text as it appears in the ASCII file.

• The Layer fields are only active when Layer is not placed in Selected Fields below. This means that the layer will not be read from the input file, so you may choose the target layer for each checked object type.

• Block Name is only active when Block name is not specified in Selected Fields below. This means that the block name will not be read from the input file, so you may choose the target block.

If the ASCII file contains object type identifiers, layers, and/or block names, you may either use them from the file or override them using Skip in Selected Fields below. For example, if the input file contains POINTs, you may insert blocks instead by Skipping the word POINT in the file and checking only Block in Object Types. The coordinates are then forced to be inserted as the block you specify.

If the file has comments embedded in it, then check on Comment indicator and enter the characters that indicate a comment line.

Set delimiter to the character(s) that separate fields in the input file.

Highlight each field that exists in the input file, then click on the >> button to add it to the Selected Fields list. Or, highlight a field in the Selected Fields list and click on << to remove it from the list.• To ignore a field, add Skip to Selected Fields.• Skip may also be used to override object type

identifiers, layers, and/or block names that exist in the file, but that you don’t want to use. If any of these are skipped, you may specify the override values in the Type Id, Layer, and/or Block Name fields above.

Sort the Selected Fields list to match the field order of the input file. Highlight a field and click on the Up or Down button to move it into the correct order.

To import only those coordinates that are inside closed polylines, check on Boundary Layer and set its Layer. Closed boundary polyline(s) should already exist (see Step 2 above).

Command: zcheck

Make selections in the dialog box and choose the OK button. The specified block will be inserted at each (X,Y) intersection that matches the layer and elevation difference criteria. Text showing the elevation difference (not the block or polyline elevation) will be inserted next to the block

The acad.dwt template drawing supplied with DAT/EM CAPTURE contains a block called LEADER. This block is an arrow designed to use with zcheck. This block, or any block, may be used to mark intersections.

ZcheckPurpose: To mark the point of intersection and the elevation difference between polylines where they intersect in the

(X,Y) plane.

Z Tolerance:• To mark all (X,Y) intersections, use a Z

tolerance of 0 (zero) or less.• (X,Y) intersections will be marked only if

the Z difference between the polylines is greater than or equal to the Z tolerance.

• For example, if z tolerance is 10, only (X,Y) intersections with an elevation difference 10 or greater will be marked.

Scale is multiplied times the map scale (Setup) to produce the block and text size.

If on, text will be inserted showing the elevation difference at the point of (X,Y) intersection. It is not the elevation of the block or polylines.

Continue to make settings in the Capture Contour dialog box:

Select a contour interval for the resulting interpolated contours. The interval is in ground units.(Required) Select a contour Layer:

• This is the intermediate contour layer if an index contour layer is selected below.

• All contours will be on this layer if an index contour layer is not selected.

(Optional) Select an index contour Layer:• Select “No index contours” from the top of the list if index

contours will not be used.• To use index contours, select a layer and an index contour

Interval. The Interval should be an even multiple of the Interval above in the Contours area.

• For example, if Contours Interval is 5.00 and Index Contours Interval is 25.00, then intermediate contours will be placed at 95.0, 105.0, 110.0, 115.0, 120.0, and 130.0, while index contours will be placed at 100.0 and 125.0.

The Minimum Contour Area setting tests the area of closed contours (tops and depressions).• If the area of a closed contour is smaller than Minimum

Contour Area, then it does not insert that contour.• This prevents “tiny circles” from cluttering the contour set.• To disable this setting and insert all contours, set to 0.0 (zero).

To erase contours on a layer other than the currently set contours and index contours layers, set an Existing Contours layer before using the Erase Existing Contours button.• To disable this setting, select the

“(Delete existing contours)” message from the top of the layer list.

• This layer is used only by the Erase Existing Contours button.

Step 7) Select OK to run the contour generation.

When OK is selected from the dialog box, the settings are used to send information to the SCOP library, which creates elevation contours. The contours are then imported into the AutoCAD file.

Step 8) View the resulting contours. If the contours seem incorrect in an area, then there may be mistakes or missing data in the mass points or morphological objects. In this case, improve the input data using any of the following methods:

• Use DTMedit (page 5-55) to edit points or morphological data;

• Add points. Note that if mass points have been added or edited, it may be useful to check on the Export DTM option on the Capture Contour dialog box.

• Add morphological data

• Edit morphological data

After editing the input data, run contour again. Use the Erase existing contours button to remove the old contours before generating the new ones.

Step 9) Repeat the review, edit, and run steps until the contours are acceptable.

Select a Smoothing setting for the resulting interpolated contours. The smoothest setting takes the longest to process.

If Grid method is selected, set a Grid Size.• If using a MATCH-T-generated input

points, enter the grid size or half the grid size that was used when running MATCH-T.

• If using a DTM grid digitized directly in AutoCAD, enter the distance between

If Export DTM is selected, all points currently in the AutoCAD file will be exported to an INPHO MATCH-T binary file. (This file may be used in a later run of CAPTURE CONTOUR or by INPHO software.

Contour may be generated based on a TIN (triangulated network) or from a grid.• If TIN is selected, choose an Optimize setting.• If Optimize is on, contours will be less jagged,

but processing time will increase. (TIN files are not saved for use with other applications.)

Troubleshooting 7

Buttons and Switches

Symptom Suggestion

A stereoplotter button or switch is pressed, but either nothing happens or the wrong thing happens. (The plotter client is running and the DAT/EM application was loaded in the CAD software.)

The buttons and switches may not be set at all or they have been set to undesired functions.

1. Use the Buttons command to view the button settings. See “Buttons” on page 5-27.

2. Change the settings if necessary.

A button or switch is pressed, but nothing happens. The switch settings are verified to be correct using the Buttons command.

Button status is shown by the plotter client. With the plotter client running, press the switch. If the plotter client does not show that the switch has been activated, then there may be a hardware problem. Contact DAT/EM support.
