Draws an arc. The default method of drawing arcs is selecting three points (so-called "3 point arc"), which are the two endpoints of the arc and some other point along its locus. Other methods of drawing an arc can be specified by three letters, such as SEA, which means "Start Point, End Point, and Included Angle." A Included angle

Dimensioning sub-command:

Draws a linear dimension with the dimension line parallel to the selected dimension origin points. This lets you align a dimension with an angled line that is not either exactly horizontal or vertical.



Dimensioning sub-command:

Draws an arc and calculates the angle between two non-parallel lines, and draws the text and arrowheads. Arrowheads are the standard AutoCAD filled triangles, regardless of your defined Arrow Block.



Dimensioning sub-command:

Continues a linear dimension from the baseline (the so-called "first extension line") of the previous or selected dimension. This is not frequently 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 baseline command, you should reset to 1/8".



Dimensioning sub-command:

Draws a pair of crossed lines at the center of a circle or arc on the current layer



Dimensioning sub-command:

Continues a linear dimension from the second extension line of the previous or selected dimension. It is used to create a so-called "string" of dimensions. This is used quite a bit in architectural drawings.



Dimensioning sub-command:

Draws a dimension through the center of a circle or arc, calculating the diameter, with one of the arrow heads located at the point on the circle or arc which is picked.



Dimensioning sub-command:

Exits the dimensioning program and returns from the Dim: prompt to the normal Command: prompt



Dimensioning sub-command:

Restores the text of an associative dimension to its default (home) location if you have moved it.



Dimensioning sub-command:

Draws a horizontal linear dimension line



Dimensioning sub-command:

Draws an a line or series of lines with an arrow head (commonly called a "leader") to point to an object to notate it. This command will also prompt you for the note at the end of the leader line, but it will allow only one line of text. The most useful method of using this command is to simply draw leaders between the object to be notated and text that you create with the DTEXT command.



Dimensioning sub-command:

Permits changing text of an associative dimension without exploding it. However, once the text has been changed, the dimension will no longer be associative.



Dimensioning sub-command:

Adjusts the obliquing angle of a linear associative dimensionsā extension lines. Useful in dimensioning isometric drawings.



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.

Draws the radius dimension of an arc or circle from the center to the point on its locus where the arc or circle was selected.



Dimensioning sub-command:

Redraws the viewport, just like the regular REDRAW command.



Dimensioning sub-command:

Makes a dimension style current



Dimensioning sub-command:

Draws a linear dimension with the distance measured origin points, but with the actual dimension line set at a different angle.



Dimensioning sub-command:

Saves the currently set dimension variables under a dimension style name for future retrieval through the RESTORE command.



Dimensioning sub-command:

Lists all dimension variables with their current status.



Dimensioning sub-command:

Switches to a new Text Style for all future dimensions.



Dimensioning sub-command:

Allows moving text in associative dimensions without having to explode the dimensions.

Undoes any changes made by the most recent dimensioning command.



Dimensioning sub-command:

Changes selected associative dimensions to use the current dimension variables, the current text style, and the current units setting.

Lists the settings of dimension variables associated with a particular dimension style.



Dimensioning sub-command:

Draws a vertical linear dimension line

L ("Lower-Left") makes the point picked become shoved to the lower-left corner of the graphics screen

P ("Previous") zooms back to whatever the last zoom, previous to the current zoom was -- AutoCAD stores about 10 of these, so you can walk backward in zoom magnification 10 times 

V ("Virtual Screen") makes the largest area available to the graphics card fill the graphics screen -- this varies with the quantity of graphics RAM that your graphics card has

W ("Window") asks you to pick the lower left corner and the upper right corner of a zoom window and then fits that window to the graphics screen

3DFACE Draws flat planes in 3D space with either 3 corners or 4 corners (3 sided or 4 sided flat planes). These are used to hide objects behind them in space to create the illusion of a solid object. 3DFACEs can also be shaded using the SHADE command, in which case the entire plane takes on the color assigned to its edges. Normally (without using the HIDE or SHADE commands, 3DFACEs are transparent, which means that objects behind them in space are visible through them, and they appear as "wireframes." I ("Invisible") this is used by typing in the letter "I" just before picking a corner point for the 3DFACE, and it will make the edge of the 3DFACE drawn from that point to the next one "Invisible" (that is, it will not be shown as a line on the drawing). This is important when joining several 3DFACEs together to cover a complex, multi-faceted surface, where you do not want the "seams" of the 3DFACEs to show in the final drawing. The visibility of edges of 3DFACEs can further be turned on or off by the AutoCAD variable "SPLFRAME." When SPLFRAME is set to 1 ("on"), both edges which have been made "Invisible" as well as normal, visible edges are shown on the drawing. When SPLFRAME is set to 0 ("off"), Invisible edges are not shown. The purpose of sometimes wanting to see invisible edges is that you may want to move, stretch, or copy the 3DFACE and if its edges are invisible, you cannot select them fopr modification. You can only select a 3DFACE by picking on a visible edge.
3DMESH Draws a 3D polygon mesh by specifying its size, in terms of the number of faces in each direction (called M and N directions), and the location in 3D space of each vertex (the corner of a face) in the mesh.
