ABOUT	Displays a dialogue box with AutoCAD version & serial numbers	can be transparent
APERTURE	Controls the size of the Object Snap "OSNAP") target box -- should set to 7	can be transparent
ARC or  A	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 C Center point of arc D Direction angle of a line tangent to the arc E Endpoint of arc L Length of chord passing thru both endpoints of the arc R Radius S Start point of arc <RET> uses the end of the last line or arc as the start point for the arc
AREA	Computes the area of any shape by selecting points at the corners of the shape, or by selecting a circle or polyline after typing or picking the "E" option	A sets "Add" mode S sets "Subtract" mode E computes area of selected circle or polyline
ARRAY	Makes multiple copies of selected objects in a rectangular (parallel with the snap rotation) or circular pattern	R rectangular array type P "polar" array type in circular pattern, you must indicate number of items and angle to fill, and whether the objects get rotated with the angle C "circular" array type in a circular pattern, you must indicate angle between items, angle to fill, and whether objects get rotated with the angle

The default method is to pick a center point and pick a point on the radius or type the radius dimension, but other methods can be selected.	2P Specifies circle by picking 2 points on the diameter 3P Specifies circle by picking 3 points through which the circle will pass D Allows entering the diameter dimension instead of radius dimension TTR Specifies circle by picking two lines, arcs or circles for the circle to be tangent to, and entering the dimension of the radius <RET> Enters radius of circle (the default)
COLOR or COLOUR	Sets the current color for subsequently drawn objects (objects drawn after the command is invoked). The default current color is a so-called "logical" color called "BYLAYER" which means that the color of the object drawn will be the color which the current layer has been set to.	can be transparent <number> sets current color to color number entered <name> sets current color to color name entered BYBLOCK sets floating entity color  BYLAYER sets current color to whatever color is assigned to the current layer

DIM	Takes you out of the drawing editor and into the semi-automatic dimensioning program built into AutoCAD. Will display a Dim: prompt on the command prompt line. To get back to the drawing editor and the Command: prompt, type the <Esc> key.
DIM1	Same as above, but only allows one dimensioning command to be used, and then takes you automatically back to the drawing editor and the Command: prompt.
DIM ALIGNED	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.
DIM ANGULAR	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.
DIM BASELINE	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".
DIM CENTER	Dimensioning sub-command: Draws a pair of crossed lines at the center of a circle or arc on the current layer
DIM CONTINUE	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.
DIM DIAMETER	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.
DIM EXIT	Dimensioning sub-command: Exits the dimensioning program and returns from the Dim: prompt to the normal Command: prompt
DIM HOMETEXT	Dimensioning sub-command: Restores the text of an associative dimension to its default (home) location if you have moved it.
DIM  HORIZONTAL	Dimensioning sub-command: Draws a horizontal linear dimension line
DIM LEADER	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.
DIM NEWTEXT	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.
DIM OBLIQUE	Dimensioning sub-command: Adjusts the obliquing angle of a linear associative dimensionsâ extension lines. Useful in dimensioning isometric drawings.
DIM ORDINATE	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.
DIM OVERRIDE	Dimensioning sub-command: Overrides the dimension variable settings on a selected dimension.
DIM RADIUS	Dimensioning sub-command: 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.

DIM ROTATE	Dimensioning sub-command: Draws a linear dimension with the distance measured origin points, but with the actual dimension line set at a different angle.
DIM SAVE	Dimensioning sub-command: Saves the currently set dimension variables under a dimension style name for future retrieval through the RESTORE command.
DIM STATUS	Dimensioning sub-command: Lists all dimension variables with their current status.
DIM STYLE	Dimensioning sub-command: Switches to a new Text Style for all future dimensions.

DIM UNDO	Dimensioning sub-command: Undoes any changes made by the most recent dimensioning command.
DIM UPDATE	Dimensioning sub-command: Changes selected associative dimensions to use the current dimension variables, the current text style, and the current units setting.
DIM VARIABLES	Dimensioning sub-command: Lists the settings of dimension variables associated with a particular dimension style.
DIM VERTICAL	Dimensioning sub-command: Draws a vertical linear dimension line

ZOOM	Enlarges or reduces the display magnification of the drawing, without changing the actual size of the entities	can be transparent <number> multiplier from original magnification <number X> multiplier from current magnification <number XP>multiplier of magnification relative to paper space -- used for plotting to get right plot scale in each viewport A ("All") fills limits of drawing to screen C ("Center") makes picked point the center of the screen D ("Dynamic") makes an adjustible rectangular lens appear on the screen which is capable of being made smaller or larger and moved to different positions over the drawing and once set by the user, the drawing will quickly zoom to the location and magnification set for the lens. This sub-command is no longer useful because all computers have very fast zooms naturally now. E ("Extents") makes the farthest edges of the actual visible drawing fill up the graphics screen 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.
