General Enhancements

The following sections describe platform and general enhancements in CADDS.

Networked Drives on Windows NT

You can now map networked drives from a Windows NT or UNIX machine onwhich CADDS 5i is running, using the following new third-party software inaddition to the existing software:

• Reflection from WRQ

• Novell Netware Version 5.0

• Diskshare from Intergraph (for accessing a Windows NT disk from UNIX)

All of these products are qualified on Windows NT. See the section, “UsingNetworked Drives on Windows NT,” in Installing CADDS 5i for details.

CVGPII Postprocessor and Intellepost on Windows NT

The CVGPII family of products that provides a series of standard postprocessorsolutions for the CVNC product family is now available on Windows NT. InWindows NT, you can also use the CVGPII postprocessor that you havecustomized on UNIX. CVGPII provides a complete solution for the generation ofmachine control data from CVNC CLFiles for most NC machine tools.

Intellepost 2000, now available on Windows NT and Windows 2000, supports theCVGPII postprocessor that you have customized on UNIX. It also supports theCADDS binary CLFiles. See the sections, “CVGPII Postprocessor onWindows NT” and “Intellepost on Windows NT,” in Installing CADDS 5i fordetails.

Setting Tolerance for System Library Features

The system library features used in the Metric part now use the tolerance value of0.05 mm instead of the previous default tolerance value that is specified in inches.

Set an appropriate Epsilon value in the configuration part (c_part) so that youcan also use a flexible tolerance (Epsilon) value for the system library features inthe Metric parts. See the Feature-based Modeling User Guide and MenuReference for details.

New Features and EnhancementsGeneral Enhancements

Best Practices

Documentation is available recommending the best practices for the followingtopics:

• Drawing Generation

• Concurrent Assembly Mock-Up (CAMU)

See the following books for the relevant documentation:

• Drawing Generation Best Practices

• CAMU Best Practices


New Features and EnhancementsDynamic Loading on Windows NT

Dynamic Loading on Windows NT

Dynamic loading that is available in CADDS 5i on UNIX is also available withCADDS 5i on Windows NT. You no longer have to assemble CADDS to add yourown commands into CADDS.

The customized commands are loaded dynamically as you use them. You do nothave to load and link CADDS when using CADDS 5i on Windows NT.

The following applications use dynamic loading on Windows NT:

• CADDS 5i ISSM

• Custom CVact menus

• The CVMAC interface and the CALLF routines

Dynamic Loading of CADDS 5i ISSM on Windows NT

CADDS 5i ISSM now incorporates dynamic loading on Windows NT. Accordingto the current procedure, you only have to link the exported symbol library to yourcode to build a Dynamically Linked Library (DLL) and use the set of new toolsprovided. The exported symbol library is available as part of the CADDS 5i ISSMpackage.

New commands are loaded dynamically as you use them. The verb-noun,modifier, and message tables are used in the same manner as in the previousreleases. See the CV-DORS User Guide for details.

Dynamic Loading of Custom CVact Menus onWindows NT

You can now dynamically load the custom CVact menus for use with CADDS onWindows NT. The CVact runtime environment allows you to compile and use onWindows NT the custom CVact menus, message repositories, and the X Pixmap(XPM 2C format) icons. Menus that you have designed using the CVact tool onUNIX can now be compiled and used with CADDS on Windows NT.

Please note: You cannot use the CVact tool itself on Windows NT. You canonly use the tool to copy the custom menus from UNIX to Windows NT.

See the section, “Using CVact Menus with CADDS on Windows NT,” in theCVact User Guide for details.


New Features and EnhancementsDynamic Loading on Windows NT

Dynamic Loading of CVMAC Using CALLF Routines

The CALLF routines and the CVMAC interface available in CADDS 5i UNIX arealso available on Windows NT. The CVMAC CALLF routines allow you to call aFORTRAN or C function from a CVMAC script.

The Perl script generates the DLLs required by the CVMAC CALLF routines andthe customized commands. The exported symbol library that you must link to yourcode to build the DLL is available as part of CADDS.

See the CVMAC Language Reference for details.


New Features and EnhancementsCADDS Centric Associative Topology Bus

CADDS Centric Associative Topology Bus

Associative Topology Bus (ATB) provides both CADDS and Pro/ENGINEERusers with a heterogeneous environment where both CADDS and Pro/ENGINEERmodels can be used for modeling and assembly work in a single CADenvironment.

You can now import Pro/ENGINEER parts and assemblies into CADDS formatfrom the CADDS environment. You can also export CADDS parts and assembliesinto Pro/ENGINEER format from the CADDS environment. You can then use theexported CADDS parts and assemblies in Pro/ENGINEER.

The ATB functionality is available through the CADDS desktop or the LDM in theParts mode, Assembly mode, and also from the Assembly Structure Window. TheATB functionality is also available through the CADDS command line interface inthe Explicit, Parametric, and Assembly environments of CADDS.

The functionality is also available through the NAV-CAMU mode of EPD EnabledCADDS 5i.

You can perform the following tasks:

• Import a Pro/ENGINEER part or assembly to CADDS thereby creating aCADDS TIM (Translated Image Model) part or assembly.

• Export a CADDS part or assembly to Pro/ENGINEER thereby creating aPro/ENGINEER TIM part or assembly.

• Verify, and if found to be out of date, update the imported CADDS TIM part orassembly.

• Verify the exported Pro/ENGINEER TIM part or assembly and, if found to beout of date, update it.

• Perform associative updates of CADDS or Pro/ENGINEER parts andassemblies. If you add parametric geometry or application data to a CADDSTIM part, and the application data references the imported geometry, theparametric geometry or application data is updated associatively to reflect thechanges in the original geometry.

See Using Associative Topology Bus Enabled CADDS 5i for details.


New Features and EnhancementsCADDS Centric Associative Topology Bus

Figure 1-1 The Nodes That Appear in a Different Font or as Dashes in the AssemblyStructure Window Are the Pro/ENGINEER TIMs.


New Features and EnhancementsThe DXF Converter

The DXF Converter

The DXF (Data Exchange Format) converter is now available in the CADDS 5iExplicit environment. The DXF converter can currently handle only 3D wireframemodel data while importing the DXF files and exporting CADDS files.

DXF is a neutral file format that is supported by Autodesk for the exchange ofCAD data across modelers.

See the section, “Importing and Exporting DXF Files,” in the Explicit ModelingUser Guide and Menu Reference for details.

Figure 1-2 Get DXF Property Sheet


New Features and EnhancementsParametric Modeling

Parametric Modeling

The following sections describe enhancements in modeling in the Parametricenvironment.

Update Ppart

If you remove commands from the source part, the corresponding geometry fromthe target part is removed, even if it has downstream users in the target part. Theinserted part is in synchronization with the source part. If the imported geometryhas a dependent geometry, using the UPDATE PPART command results inregeneration failure.

See the section, “Update Parametric Part,” in the Parametric Modeling User Guideand Menu Reference for details.

Edit Ppart

You can now preserve the tag names of the imported parametric or explicit entitiesfrom the replaced source part using the NEW PART option of the EDIT PPARTcommand. The tag names of only those entities of the replaced source part arepreserved that match the entities of the original source part.

Please note: Use the COPYTAG option of the INSERT PPART command toimport the replaced source part entities. Using this option will preserve the entitytag names of the replaced source part.

See the section, “Edit Parametric Part,” in the Parametric Modeling User Guideand Menu Reference for details.

Reuse History

You can now orient the copied geometry by applying geometrical transformationsusing the REUSE HISTORY command. The transformation supports thetranslation and rotation of the copied geometry about any axis that you specify.Use the Layer option to place the copied geometry on a layer of your choice. Youcan also import geometry that is associated with the SMD application data usingREUSE HISTORY.



Figure 1-3 Reusing History with the Transform Option

Example: The following example demonstrates the use of the REUSE HISTORYcommand within the same source part with transformations.

Figure 1-4 The Source Part

The following part shows how the REUSE HISTORY command is used within thesame part by specifying a new origin and a 210-degree rotation about the z-axisand subsequent parameter changes.



Figure 1-5 Copied Geometry Within the Source Part with Transformations

See the section, “Copying Part History,” in the Parametric Modeling User Guideand Menu Reference for details.

Performing History Operation Using Unified HistoryMenu

The History Operations property sheet is now introduced to simplify theperformance of history operations. You can select commands from a runtime list ofthe part history commands and perform the required action using the commandsyou have selected.



Figure 1-6 The History Operations Property Sheet

Based on the selection of commands from the runtime list of the part historycommands, you can select the operation on the History Operations property sheet.Operations that are not relevant to the selected commands are not available on theHistory Operations property sheet.

For example, if you select a command that is not of type Apply Sketch, then theEdit Sketch and Replace Sketch operations are not available on the HistoryOperations property sheet.

Sweeping a Face with Initial Offset Angle

You can sweep a profile or a face with an initial offset angle using the newOFFSET ANGLE option of the INSERT ROTATIONALSWEEP command.

To perform a rotational sweep between any start and end angles, specify the totalsweep and the initial offset angles.

See the section, “Conducting Sweep Operations,” in the Parametric ModelingUser Guide and Menu Reference for details.



Figure 1-11 Results of Rotational Sweep with the Initial Offset Angle Specified


New Features and EnhancementsPlotting

Plotting

The following sections describe enhancements in plotting in both environments ofCADDS.

Plotting the Raster Output

The PLOT DOT command is enhanced to support alternative raster output formatssuch as GIF and JPEG. The new GIF option produces raster output in the GIF87format. The new JPEG option produces raster output in the JPEG format.

You can view these GIF and JPEG files using any raster file image viewer. You canalso specify the plotter settings for the raster output.

Figure 1-12 The Plot Dot Property Sheet with the GIF Option Selected

See the Explicit Modeling User Guide and Menu Reference and the ParametricModeling User Guide and Menu Reference for details.


New Features and EnhancementsPlotting

Plotting the History Tree and the Assembly Structure

You can now plot the history tree of an active part or the assembly structure of anactive assembly to a disk file or a plotter using the new PLOT TREE command.

• Use PLOT TREE HISTORY to plot the history tree in the Parametricenvironment.

• Use PLOT TREE ASSEMBLY to plot the assembly structure in the Assemblyenvironment.

You can choose to plot a node of a history tree or the assembly structure alongwith its dependent nodes.

See the Concurrent Assembly Mock-Up User Guide and Menu Reference, theParametric Multipart Design User Guide and Menu Reference, and the ParametricModeling User Guide and Menu Reference for details.


New Features and EnhancementsDrafting and Dimensioning

Drafting and Dimensioning

The following sections describe enhancements in Context Sensitive Dimensioning(CSD). See the Design and Drafting User Guide and Menu Reference for details.

Enhancements in CSD

CSD now allows you to perform the following tasks:

• Track the primary and secondary tolerances automatically.

For example, if you add a primary tolerance value, the tolerance value isautomatically converted to a rounded secondary tolerance value and is thenstored in a stack.

• Modify the Feature Control Symbols (FCS) that are created in the ANSI andISO standards without exiting the CSD environment.

• Store the information on intersecting dimensions.

This information is useful if you have a dimension that has been created usingintersection points.You can use the intersection information to modify theentities that are selected for intersection. The intersection points are thenrecalculated and the dimension changed accordingly.

• Align multiple dimensions simultaneously in the Modify Dimensions mode.

Only dimensions that belong to the same type of entities are selected foralignment and grouping.

• Group together a set of dimensions.

You can also drag the group of dimensions and break a dimension from thegroup.

Aligning Dimensions

You can align two or more dimensions simultaneously.

Aligning Two Dimensions

Move the cursor over a dimension and select it using the select mouse button. Thedimension is highlighted. Select another dimension similarly. The two dimensionsare automatically aligned when you release the mouse button.

Please note: Do not move the mouse after you select the dimensions.



Aligning Multiple Dimensions

When aligning multiple dimensions, ensure that you select dimensions that belongto a similar type of entity.

By Selecting Entities: The dimensions you select must belong to one of thefollowing categories:

• Horizontal

• Vertical

• Point-to-point

• Angular

Select multiple dimensions by holding down the Shift key and clicking the selectmouse button on the dimension entities. Release the Shift key only after youhave selected all the entities. The dimensions are automatically aligned with thedimension of the first entity that you selected.

Please note: Keep the mouse very still when selecting the entity with theselect mouse button. Otherwise, the action is registered as a drag operation insteadof a selection.

By Selecting Entities in a Window: Select the dimensions that requirealignment in a crossing window. Move the mouse with the select button and theShift key pressed to create the crossing window.

New Features and EnhancementsIntegrated 3D Sketcher

Integrated 3D Sketcher

The following sections describe enhancements in Sketcher. These enhancementsare provided with an intent to allow the migration of DesignView functionality toSketcher.

See the Integrated 3D Sketcher Menu and Technical Reference for details on eachof these enhancements.

Importing DesignView Profiles

You can now import DesignView profiles into Sketcher. The new DesignViewoption in the Open Sketch menu displays a runtime list of all the DesignViewprofiles. When you select a .dv file from the runtime list, a sketch of theDesignView profile is created and saved with the same name and equivalentSketcher geometry. You can then save this sketch profile under a new name usingFile Sketch w/Options from the resultant File menu.

Angular dimensions, text and preview information, crosshatches, variables, andequations related to DesignView geometry are not imported into Sketcher.

Fillets and chamfers are imported as arcs and lines, respectively. You cannotimport construction entities and geometric constraints. However, you can importthe point-on-curve constraint and infer horizontal and vertical constraints.

Importing Explicit Geometry Directly

You can now import explicit geometry into Sketcher, facilitating the import ofIGES or DXF data into Sketcher through the Explicit environment. The importedgeometry has no model association, unlike the import of parametric geometry.

Defining a Cplane in Sketcher

The Open Sketch menu is now available with a new Define Cplane option that isvalid only for new sketches and not for applied sketches. The Cplane that youdefine is the active Cplane and is used to define the Vpane.



Figure 1-15 The Open Sketch Property Sheet with the Define Cplane Option

Redefining a Vpane

You can redefine the sketch Vpane with an existing Cplane using the ExistingCplane option on the Virtual Pane of Glass menu. When you choose this option,the Select Cplane menu displays a list of all the available Cplanes, including theuser-defined Cplanes. When you select a Cplane from the list, a new Vpane iscreated using the selected Cplane. The sketch geometry is regenerated on the newVpane.

You can also graphically select a Cplane as you can in the Parametricenvironment.

Previewing Sketch Library

You can preview the selected library sketch without actually opening the sketchusing the new Preview Sketch option on the Open Sketch menu. This is similar tothe Browse Profile option that you can use to preview DesignView profiles. Youcan view a scaled-down version of the selected sketch in a specified rectangulararea.



Figure 1-16 Preview of the Scaled-Down Version of the Selected Library Sketch in aSpecified Rectangular Area

Editing and Applying Sketches

You can now apply the sketch geometry as elementary curves using the optionApply and Exit Sketch w/Options on the File Sketch menu.



Figure 1-17 The Apply Sketch Property Sheet with the Apply as Polycurve Option

The new Edit Sketch option on the Open Sketch menu enables you to apply one ofthe following without opening the sketch:

• Library sketch

• DesignView profile

• Legacy profiler sketch

Figure 1-18 The File Sketch Menu with the Part Library and the Sketch Library Options

Sketches created in a part are now saved in the _fd file. The _sk directory is notcreated within the part database. The sketches that are applied and unapplied,created, or used during modeling are filed in _fd. For legacy parts created beforeRelease 12, the sketches in the _sk directory of the part database are moved to_fd when the part is filed on Release 12.



Ascertaining Status of Geometry

A new Solver Status option in the Environment globals area reflects the currentstatus of the sketch geometry. The geometry appears red if it is underconstrainedand green when fully constrained.

Creating Point Entity

You can place equally spaced points on a curve using the modified DimensionPuck option in the Sketcher task set. You can use these points as references tocreate other entities. These point entities can be constrained with other Sketcherentities.

Please note: Select the line or the curve before you select the DimensionPuck option.

Figure 1-19 Equally Spaced and Constrained Point Entities on the Selected Line



Figure 1-20 Equally Spaced Point Entities on a Selected Arc and a Line

You can also create standalone point objects. Use the Construction Entity optionto select either a point object or a dimension puck.

Mirroring and Sewing Functions

Assist lines for mirroring and sewing are now enhanced. Alert windows are nowdisplayed if you do not select entities for mirroring or sewing.

Figure 1-21 Alert Window Prompting You to Select the Entities for Mirroring

You can now select a continuous loop of entities for sewing using the parametricCHAIN option from the Selection area of the top bar.



Figure 1-22 Mirroring Geometry Using Options on the Duplicate Entity Property Sheet

Selecting by Window for Import

You can use the window selection method to select multiple entities for the importof CADDS geometry.

Creating Chamfers

You can create a chamfer at a selected vertex or between two entities using the newChamfer option in the Sketcher task set. The vertex can be a hotspot shared bytwo entities that are not parallel or an autotrimmed point between two closedobjects.



Figure 1-23 A Vertex Chamfer

Figure 1-24 A Chamfer Between Two Entities at a Specific Angle



Figure 1-25 Chamfers at the Vertex, Between Two Lines, and at a Specified Angle

Any chamfer created between or on closed objects is now persistent. You can alsoconvert chamfers to construction entities.

Please note: Use the right mouse button to select the chamfer and change thedistance of the chamfer from the point of insertion on the two lines.



Filleting

In addition to creating a vertex fillet, you can now create two-entity andthree-entity fillets in Sketcher as in the Parametric environment. The Fillet optionin the Sketcher task set now includes the following options:

• Two-Entity Fillet

• Three-Entity Fillet

Figure 1-26 Two-Entity and Three-Entity Fillets



Any fillet created between closed objects is now persistent. You can convert filletsto construction entities and add the equal radius constraint to them.

Creating Pattern Geometry

You can now create pattern geometry similar to the mirroring of geometry. Thepatterns can be linear or angular.

The Duplicate Entity option in the Environment globals area now has the newoptions, Angular Pattern and Linear Pattern.

• The Linear Pattern option offsets the geometry by a constant linear distance.You can duplicate a sketch entity or a group of entities along a specifieddirection to form a linear pattern.

You can create a linear pattern just as you would create a rectangle as shown inthe following figures:

Figure 1-27 A Unidirectional Linear Pattern of Circles Offset in a Linear Distance

Figure 1-28 A Bidirectional Linear Pattern of Circles Offset in a Linear Distance



Figure 1-29 A Rectangle Duplicated and Offset by Constant Linear Distance



• The Angular Pattern option offsets the geometry by a constant angularspacing. You can duplicate a sketch entity or a group of entities to form acircular pattern with a specified angular spacing. The created pattern isassociative by default. The copies of the sketch entities are equally spaced on apitch circle. You can create an angular pattern just as you would create an arc asshown in the following figure:

Figure 1-30 An Angular Pattern of Circles Offset by Constant Angular Spacing

Figure 1-31 A Circular Pattern of Circles Offset by Constant Angular Spacing



Figure 1-32 An Angular Pattern of Rectangles Duplicated and Offset by Constant AngularSpacing



Perform either one of the following operations to break the pattern associativity:

• Remove the label

• Delete the construction entity

Creating Offsets and Thin Walls

The Sketcher task set has the Offset option. You can offset profiles and createthin-walled objects. You can select an object and offset it to a specified distance bydefault.

Figure 1-33 A Thin-Walled Object Offset on One Side and Closed by Arcs

Figure 1-34 A Thin-Walled Object Offset on Both Sides and Closed by Arcs

Use the Thin Wall option to create a thin-walled object or derive a closed object byoffsetting the object. The distance by which the object is offset is the thickness thatis created. You can close the ends by specifying lines or bisecting arcs.



Using New Environment Menu Options

The Environment menu now allows you to change the default color settings fordimensions and constraints. You can also change the highlight colors and colorsettings for construction entities, guidelines, model references, and hotspots.

• The Snap to Geometry option allows you to snap to the existing geometryand guidelines.

• The Marker Scale Factor option allows you to control the size of the hotspotand constraint graphics, object handles, and reference points.

• The Snap Range option allows you to set the snap range to a small, medium,or large value so that you can avoid snapping to entities that are not required.

• The Color Setup option allows you to change the color of the sketch.

You can set the default values for the environment variables in a file called.cadds5sketch in your home directory. You can then change the settings duringa Sketcher session.

Using Other Parametric Options in Sketcher

The following parametric options are now available in Sketcher:

• The Selection Setup option allows you to change the colors of the selectedsketch entities. Access this option through the SETUP option on the top bar.

• The Parameter Setup menu allows you to change the color of the parameters,dimensions, and constraint graphics.

• The Display Attribute Setup option allows you to change the color and font ofthe construction entity. Access this option through the CONSTRUCT option ofthe SETUP menu.

Grid changes are now persistent across Sketcher and Parametric environments.


New Features and EnhancementsInteractive Surface Design

Interactive Surface Design

The following sections describe enhancements in Interactive Surface Design(ISD).

See the Interactive Surface Design Menu and Technical Reference for details oneach of these functionalities.

Geometric Loft

New geometric lofts in ISD follow.

Draft Line Unidirection, Bidirection, and Up to aPlane Method: You can create a lofted surface with a line crosssection using asingle guide curve or a guide curve and a planar shell. You can control theorientation of the line profile by specifying a draft angle and a draft direction.

Figure 1-35 A Draft Line Loft up to a Planar Surface with an Arc as a Guide Curve

Two Guide Lines: You can create a lofted surface with a geometric line profilealong two guide shells or along a guide shell and a polycurve. The line profile to belofted lies on the plane normal to the tangent of the spine.



Figure 1-36 A Loft Surface with Two Guide Surfaces, a Line as Spine, and Another Line asthe Lofted Profile

Figure 1-37 A Line Loft with One Guide Shell and One Guide Curve

Profile Loft (One Center-Guide Closed Multi Profile)

You can create a lofted surface blending one or more closed three-dimensionalprofiles along a center guide curve. The profiles may or may not be in place. Youcan blend the profiles using the linear or cubic laws of variation. You can also use



the law of variation to modify the cross-sectional area of the lofted surface.Thevalue of the law of variation can vary between 0.0 and 1.0.

Tangency Constraints on a Lofted Surface

You can interactively select a vector field attached to the first or the last guidecurve or both, and use it to constrain the lofted surface. Constraining a loftedsurface using a vector field depends on the type of the lofted surface and thenumber of guides. The constraint on the lofted surface is defined by the normaldirection of the tangent vector field. Any change in the magnitude of the vectorfield does not affect the shape of the resultant lofted surface.

Figure 1-38 Results of the Conic Rho Loft with the Guides as Curves on Surfaces withVector Field Tangency Constraints Applied



Figure 1-39 An Arc Loft Using a Guide Shell and a Guide Curve on a Shell with Vector FieldConstraint Applied

Scaling and Blending Profiles of a Lofted Surface

You can now selectively scale the profiles while creating a profile loft using twoguide curves. The scaling is along the x-direction between the two guides or alongthe y- and z-directions. You can also blend the profiles when creating the loftedsurface with at least two profiles, using the cubic or linear law of variation. Thevalue of the law of variation can vary between 0.0 and 1.0.



Break at Curvature Discontinuity

You can divide a lofted surface at the joints of a guide polycurve that has curvaturediscontinuity to better approximate the lofted surface.

Creation of Construction Planes

You can define various Cplanes within ISD to create geometry in a moreconvenient and flexible manner. Modifying a Cplane updates the geometry createdin that Cplane and the corresponding model tree. You can also rotate the Cplaneabout any axis.

Selection of Entities

You can now use the selection options available from the Selection area of theCADDS desktop in ISD. You can select entities using different methods such asindividual selection, selection by a given name, attribute, layer, and group, or bydefining window borders. You can also use filters for selection.

Filleting

You can now create a fillet between two planar or nonplanar multisegmentpolycurves or surface curves. The fillet between the two multisegment polycurvesis tangent to both the polycurves. For planar polycurves, the fillet is in the sameplane on which the polycurves are coplanar. The fillet between nonplanarpolycurves is on the surface of a hypothetical cylinder encapsulated between thepolycurves. The axis of the fillet is perpendicular to the best fit plane for both thepolycurves and passes through the center of the fillet.

Creation of Geodesic

You can create a geodesic of a specific length in a given direction from a pton on asurface curve or on a curve lying on the surface.



Figure 1-40 A Geodesic

Join and Divide Options

The JOIN command now allows you to modify the operand curves in theModification mode. The At Position option on the Divide Curve menu allows youto selectively add or remove the ptons at which the curve must divide.

Section Curve in Parametric History

You can create a copy of a section curve and save this new section curve in theparametric history database. A plane gets attached to this section curve. You canmodify the section curve using this plane.

Model Referencing

You can create a polygon curve with model references like End of and Mid ofusing the Coordinate menu. You can modify the data point of a dataset and thepolygon point of a polygon curve with reference to a model.



Modifying the Surface Degree

You can now modify the u-degree and v-degree of a basic or lofted surface. Youcan also change the existing degree using the Degree option in the Constraintsmenu.

The Undo Option

With the UNDO option, you can restore a model to the state before the lastmodification.

Tag Assignment and Removal

You can now assign or remove the tag name of an ISD entity.

Pton on Polycurves

You can now create ptons on a multisegment polycurve using the Pton option fromthe task set.

Selective Shading

You can now selectively shade the faces of a shell or a shell from a view.

Dynamic Sectioning

A new option now enables dynamic sectioning in ISD. You can now create a planeon a curve pton and dynamically drag this plane along the curve. The section curveis updated simultaneously.

Global Normalized Parameter

If there is a change in the topology of a curve or a surface, ptons are now updatedand stored based on global normal parameters. This method of storage helps theregeneration of commands.

Highlight Dependency

You can now select an entity and display the dependent entities using the HighlightDependency option in the Parameter menu.



Other Menu Enhancements

The following are additional menu enhancements:

• The Data Set Read menu is now consistent with the other ISD menus.

• The DataPoint External Constraint menu is enhanced so that the vector nolonger determines the magnitude. The vector defines the direction only andmust be specified in units in the Fillin field.
