ARCor

A

Draws an arc. The default method ofdrawing arcs is selecting three points (so-called "3 point arc"), which are the twoendpoints of the arc and some other pointalong its locus. Other methods of drawingan arc can be specified by three letters,

such as SEA, which means "Start Point,End Point, and Included Angle."

DIM Takes you out of the drawing editor andinto the semi-automatic dimensioningprogram built into AutoCAD. Will display aDim: prompt on the command promptline. To get back to the drawing editor andthe Command: prompt, type the


6/34

key.

DIM1 Same as above, but only allows onedimensioning command to be used, andthen takes you automatically back to thedrawing editor and the Command:

prompt.

DIMALIGNED

Dimensioning sub-command:Draws a linear dimension with thedimension line parallel to the

selected dimension origin points.

This lets you align a dimension withan angled line that is not either

exactly horizontal or vertical.

DIMANGULAR

Dimensioning sub-command:Draws an arc and calculates theangle between two non-parallellines, and draws the text and

arrowheads. Arrowheads are the

standard AutoCAD filled triangles,regardless of your defined Arrow

Block.

DIMBASELINE

Dimensioning sub-command:Continues a linear dimension fromthe baseline (the so-called "first

extension line") of the previous or

selected dimension. This is notfrequently used in architectural

dimensions. The spacing between

each dimension line is controlled by

the AutoCAD variable DIMDLI("Dimension Line Increment"),

which you should set at 0 normally,

but if you use the baselinecommand, you should reset to 1/8".

DIMCENTER

Dimensioning sub-command:Draws a pair of crossed lines at the

center of a circle or arc on the

current layer

DIMCONTINUE

Dimensioning sub-command:Continues a linear dimension from


7/34

the second extension line of theprevious or selected dimension. It is

used to create a so-called "string" of

dimensions. This is used quite a bitin architectural drawings.

DIMDIAMETER

Dimensioning sub-command:Draws a dimension through the

center of a circle or arc, calculating

the diameter, with one of the arrowheads located at the point on the

circle or arc which is picked.

DIMEXIT

Dimensioning sub-command:Exits the dimensioning program

and returns from the Dim: promptto the normal Command: prompt

DIMHOMETEXT

Dimensioning sub-command:Restores the text of an associativedimension to its default (home)

location if you have moved it.

DIM

HORIZONTAL

Dimensioning sub-command:Draws a horizontal linear dimensionline

DIMLEADER

Dimensioning sub-command:Draws an a line or series of lines

with an arrow head (commonly

called a "leader") to point to anobject to notate it. This command

will also prompt you for the note at

the end of the leader line, but it willallow only one line of text. The most

useful method of using this

command is to simply draw leaders

between the object to be notatedand text that you create with the

DTEXT command.

DIMNEWTEXT

Dimensioning sub-command:Permits changing text of an

associative dimension without


8/34

exploding it. However, once the texthas been changed, the dimension

will no longer be associative.

DIMOBLIQUE

Dimensioning sub-command:Adjusts the obliquing angle of alinear associative dimensions

extension lines. Useful in

dimensioning isometric drawings.

DIMORDINATE

Dimensioning sub-command:Draws the X and Y coordinates

within a box with a leader line

attached to the point, for a selected

point. Automatically calculates the

coordinates.DIMOVERRIDE

Dimensioning sub-command:Overrides the dimension variable

settings on a selected dimension.

DIMRADIUS

Dimensioning sub-command:Draws the radius dimension of an

arc or circle from the center to the

point on its locus where the arc orcircle was selected.

DIMREDRAW

Dimensioning sub-command:Redraws the viewport, just like the

regular REDRAW command.

DIMRESTORE

Dimensioning sub-command:Makes a dimension style current

DIMROTATE

Dimensioning sub-command:Draws a linear dimension with the

distance measured origin points, butwith the actual dimension line set ata different angle.

DIMSAVE

Dimensioning sub-command:Saves the currently set dimension

variables under a dimension stylename for future retrieval through


9/34

the RESTORE command.

DIMSTATUS

Dimensioning sub-command:Lists all dimension variables with

their current status.

DIMSTYLE

Dimensioning sub-command:Switches to a new Text Style for allfuture dimensions.

DIMTEDIT

Dimensioning sub-command:Allows moving text in associative

dimensions without having to

explode the dimensions.

DIMTROTATE

Dimensioning sub-command:Allows rotation of the text of several

associative dimensions at once.

DIMUNDO

Dimensioning sub-command:Undoes any changes made by themost recent dimensioning

command.

DIMUPDATE

Dimensioning sub-command:Changes selected associativedimensions to use the current

dimension variables, the current

text style, and the current unitssetting.

DIMVARIABLES

Dimensioning sub-command:Lists the settings of dimension

variables associated with a

particular dimension style.

DIMVERTICAL

Dimensioning sub-command:Draws a vertical linear dimension

line

DIST Finds distance between two points can be transparent

DIVIDE Places points along a line, polyline, arc, or circle, dividing it into the specified numberof equal parts

EXPLODE Separates a block, dimension or hatchpattern into its constituent entities or

makes a polyline into a series of straightlines. In the case of a block that isexploded, if it was originally drawn on the0 layer, it returns to that layer, regardlessof the layer it was inserted on, and it losesits referential connection to the originalblock. In the case of a dimension or hatchpattern that has been exploded, theirparts go back to the 0 layer, and areassigned the logical color (BYBLOCK)regardless of the layer they were drawnon. In the case of an exploded polyline, itloses any width it may have had.

A ("All") fills limits of drawing to

screenC ("Center") makes picked point thecenter of the screenD ("Dynamic") makes an adjustiblerectangular lens appear on thescreen which is capable of beingmade smaller or larger and moved todifferent positions over the drawingand once set by the user, thedrawing will quickly zoom to thelocation and magnification set for thelens. This sub-command is no longer

useful because all computers havevery fast zooms naturally now.E ("Extents") makes the farthestedges of the actual visible drawing fillup the graphics screenL ("Lower-Left") makes the pointpicked become shoved to the lower-left corner of the graphics screenP ("Previous") zooms back towhatever the last zoom, previous to

the current zoom was -- AutoCADstores about 10 of these, so you canwalk backward in zoom magnification10 times

V ("Virtual Screen") makes thelargest area available to the graphicscard fill the graphics screen -- thisvaries with the quantity of graphicsRAM that your graphics card hasW ("Window") asks you to pick thelower left corner and the upper rightcorner of a zoom window and then

fits that window to the graphicsscreen

3DFACE Draws flat planes in 3D space with either 3 corners or 4 corners (3 sided or 4 sidedflat planes). These are used to hideobjects behind them in space to createthe illusion of a solid object. 3DFACEscan also be shaded using the SHADEcommand, in which case the entire plane

important when joining several3DFACEs together to cover acomplex, multi-faceted surface,where you do not want the "seams"of the 3DFACEs to show in the finaldrawing. The visibility of edges of

3DFACEs can further be turned on oroff by the AutoCAD variable"SPLFRAME." When SPLFRAME isset to 1 ("on"), both edges whichhave been made "Invisible" as wellas normal, visible edges are shownon the drawing. When SPLFRAME isset to 0 ("off"), Invisible edges are notshown. The purpose of sometimeswanting to see invisible edges is thatyou may want to move, stretch, orcopy the 3DFACE and if its edgesare invisible, you cannot select them

fopr modification. You can only selecta 3DFACE by picking on a visibleedge.

3DMESH Draws a 3D polygon mesh by specifyingits size, in terms of the number of faces ineach direction (called M and N directions),and the location in 3D space of eachvertex (the corner of a face) in the mesh.
