Format:     AREA  First point: (point)
            Next point:  (point)
            Next point:  (point)
            Next point:  ...press RETURN to end point entry

Reference:  Section 5.3 of User Guide.
\ARRAY
The  ARRAY  command makes multiple copies of selected objects, in a
rectangular or circular pattern.

Format:     ARRAY  Select objects or Window or Last: (select)
            Rectangular or circular array (R/C):

For a rectangular array, you are asked for the number of columns and 
rows, and the spacing between them.

For a circular array, you must supply a center point, the angle between
items, and the number of items (or the angle to be covered).  Optionally,
you can rotate the items as the array is drawn.

Reference:  Section 5.2 of User Guide
\ATTDEF
The  ATTDEF  command creates an Attribute Definition (ADE-2 feature).
First, you specify the modes for this Attribute Definition.  The modes are:

   Invisible  - Do not display, but allow extraction.
   Constant   - All occurrences of this Attribute have the same Value.
   Verify     - Issue extra prompts to verify a proper Value.

Format:     ATTDEF  Attribute modes  --  Invisible:N  Constant:N  Verify:N
            Enter (ICV) to change, RETURN when done:

The tag, prompt, and default value for the Attribute are then requested,
as are its location, height, and rotation angle.

            Attribute tag: (up to 31 chars; letters, digits, $, -, _)
            Attribute prompt:
            Default attribute value:
            Starting point or (ACRS):
            Height <default>:
            Rotation angle <default>:

Reference:  Section 11.2 of User Guide.
\ATTDISP
The  ATTDISP  command (ADE-2 feature) can be used to override the visibility
mode set for Attributes on a global basis.

Format:     ATTDISP  Normal/On/Off <current>:

   Normal  - Visible Attributes are displayed, invisible Attributes are not.
   On      - All Attributes are made visible.
   Off     - All Attributes are made invisible.

Reference:  Section 11.3 of User Guide.
\ATTEDIT
The  ATTEDIT  command (ADE-2 feature) allows you to modify certain aspects
of Attributes independent of the Blocks in which they reside.  You can
perform global or individual editing, and you can restrict the operation
to certain Blocks, Attribute Tags, and Attribute Values, or to just those
Attributes that are currently visible on the screen.

Format:     ATTEDIT  Edit Attributes one by one? <Y>  (N = global)
            Block name specification <*>:
            Attribute tag specification <*>:
            Attribute value specification <*>:

Reference:  Section 11.4 of User Guide.
\ATTEXT
The  ATTEXT  command (ADE-2 feature) is used to extract Attribute information
from a drawing for analysis by another program or for transfer to a database.

Format:     ATTEXT  CDF, SDF, or DXF attribute extract? <C>

   CDF - Comma Delimited Format
   SDF - Fixed-field format
   DXF - Drawing interchange format

CDF format is the default, since it is simplest to read and permits
selective extraction of just the desired Attributes.

Reference:  Section 11.5 of User Guide.
\AXIS
The  AXIS  command controls the display of axes, or ruler lines,
along the edge of the graphics display.  This is an ADE-1 feature.

Format:     AXIS  On/Off/Tick Spacing(X)/Aspect:

The axis display can be turned on and off, and the tick spacing can be
specified in terms of drawing units or as a multiple of the Snap
resolution.  For example, a value of "5X" would place a tick mark
at every fifth Snap point.  

The "Aspect" option is an ADE-2 feature that allows you to set
different tick spacing for the horizontal and vertical axes.

Reference:  Section 8.3 of User Guide
\BASE
The  BASE  command is defines a reference point for insertion
and rotation of the current drawing in subsequent drawings.

Format:     BASE  Base point:  (point)

Reference:  Section 9.4 of User Guide.
\BLIPMODE
The  BLIPMODE  command controls the generation of marker "blips" - the 
small temporary marks drawn whenever you designate a point.   When 
BLIPMODE is "On", blips are drawn; when "Off", blips are suppressed.

Format:     BLIPMODE  On/Off <current>:

Reference:  Section 6.9 of User Guide
\BLOCK
The  BLOCK  command allows you to name a group of objects that can
then be INSERTed as a unit anywhere in the current drawing, with 
specified X and Y scales and rotation.

Format:     BLOCK  Block name (or ?):  (name)
            Insertion base point:  (point)
            Select objects or Window or Last:  (select)

If you respond to the "Block name" prompt with a "?", AutoCAD will
list the names of all Blocks currently defined in this drawing.

Reference:  Section 9.2 of User Guide.
\BREAK
The  BREAK  command deletes part of a line, trace, circle, or arc.
This is an ADE-1 feature.

Format:     BREAK  Select object: (select one object)
            Enter first point: (point)
            Enter second point: (point)   

You can break a line, trace, or arc into two sections, or cut one end
off.  If you break a circle, it changes to an arc by deleting the
portion from the first point to the second, going counterclockwise.

If you select the object by pointing to it, the break is assumed
to begin at the selection point, and the next prompt is:

            Enter second point or F:

If you want to begin the break at a point where some other object
intersects with the object to be broken, choose an unambiguous point
to select the object, and then enter "F" in response to this prompt.
You can then select the beginning and ending points of the break.

Reference:  Section 5.2 of User Guide
\CHAMFER
The  CHAMFER  command trims two intersecting lines (or two adjacent 
segments of a Polyline) at a given distance from their intersection and 
connects the trimmed ends with a new line.   Different trim distances can 
be set for the two lines, and are retained with the drawing.   If the 
specified lines do not intersect, CHAMFER will extend them until they do, 
and then proceed as above.   If the ADE-3 package is present, chamfers can 
be applied to an entire Polyline, chamfering all the intersections.

Format:     CHAMFER  Polyline/Distances/<select first line>:

   D - Set chamfer distances
   P - Chamfer entire Polyline

Reference:  Section 5.2.9 of User Guide
\CHANGE
The  CHANGE  command allows you to modify the properties of existing objects
in the drawing.

Format:     CHANGE   Select objects or Window or Last:  (select)
            Change point (or Layer or Elevation):

In the following descriptions, the selected Change Point is abbreviated
"CP".  If the ADE-2 package is present, the selected point can be dragged.

   Line   - Endpoint closest to CP changes to CP (ORTHO can affect this).
   Circle - Radius changes so that CP is on circumference.
   Block  - Location changes to CP.  New angle may be specified.
   Text   - Location changes to CP.  New text style, height, angle,
            and text string may be specified.
   Attribute Definition - Same as Text, plus Attribute tag may be changed.

\
Any entity's layer can be changed by replying "L" when prompted
for the change point.

Format:     CHANGE  Select objects or Window or Last:  (select)
            Change point (or Layer or Elevation):  L
            New layer:

If the ADE-3 package is present, any entity's elevation or thickness,
can be changed by replying "E" when prompted for the change point.

Format:     CHANGE  Select objects or Window or Last:  (select)
            Change point (or Layer or Elevation):  E
            New elevation:
            New thickness:

Reference:  Section 5.2 of User Guide.
\CIRCLE
The  CIRCLE  command is used to draw a circle.  You can specify the circle
using a center point and radius.

Format:     CIRCLE  Center point (or 3P or 2P):  (point)
            Radius (or D):  (radius value)

To specify the radius, you can designate a point to be on the circumference.
ADE-2 users can enter "DRAG" in response to the "Radius (or D)" prompt to
specify the circle size visually.

If it is more convenient to enter the diameter than the radius, reply to the
"Radius (or D)" prompt with a "D".

The circle can also be specified using three points on the circumference
(reply "3P" when prompted for the center point), or by designating two
endpoints of its diameter (reply "2P").  For these methods, you can "drag"
the last point if you have the ADE-2 package.

Reference:  Section 4.3 of User Guide.
\COLOR
\COLORS
Drawing colors are controlled by the  LAYER  command.

Color numbers 1 through 7 have standard meanings as follows:

         1 - Red
         2 - Yellow
         3 - Green
         4 - Cyan
         5 - Blue
         6 - Magenta
         7 - White

Reference:  LAYER command, Section 7.7 of User Guide
\COPY
The  COPY  command is used to duplicate one or more existing drawing
entities at another location without erasing the original.

Format:     COPY  Select objects or Window or Last:  (select)
            Base point or displacement:
            Second point of displacement:  (if base selected above)

If you have the ADE-2 package, you can "drag" the object into position
on the screen.  To do this, designate a reference point on the object in
response to the "Base point..." prompt, and then reply "DRAG" to the
"Second point:" prompt.  The selected objects will follow the movements
of the screen crosshairs.   Move the objects into position and then press 
the pointer's "pick" button.

Reference:  Section 5.2 of User Guide.
\DBLIST
The  DBLIST  command produces a complete list of the contents
of the drawing database for the current drawing.  This command
is used mostly for debugging.

Format:     DBLIST

You can use CTRL S to pause, and CTRL C to cancel the listing.
If you want to echo the listing to your printer, use CTRL P.

Reference:  Section 5.3 of User Guide.
\DELAY
The  DELAY  command is used in command scripts to allow the display
to be viewed before the next command is automatically issued.  DELAY
times are designed to be approximately 1 millisecond per increment, but
are ultimately a function of the computer equipment running AutoCAD.

Format      DELAY  Delay time in milliseconds:  (number)

The larger the number, the longer the delay.

Reference:  Command scripts, Section 10.3 of User Guide
\DIM
The DIM command (ADE-1 feature) enters Dimensioning mode.  To return to normal
command mode, respond to the "Dim:" prompt by entering the EXIT command or
CTRL C.  The commands allowed during Dimensioning mode are listed below.
Each may be abbreviated to its first three characters.

Reference:  Section 10.1 of User Guide.
\DIST
The  DIST  command displays the distance (in drawing units), the angle,
and the delta-X/Y between two designated points.

Format:     DIST  First point:  (point)
            Second point: (point)

If a single number is entered in response to the "First point:" prompt,
DIST displays that number in the current UNITS format (ADE-1 feature).

Reference:  Section 5.3 of User Guide.
\DRAG
\DRAGMODE
If the ADE-2 package is present, the ARC, CIRCLE, INSERT, SHAPE, COPY,
MOVE, and CHANGE commands allow you to "drag" the object into position
visually.  Dragging is turned on by entering the word "DRAG" at
appropriate points in the command prompt sequence.

The  DRAGMODE  command can be used to disable dragging if you find it too
slow on your display.  "DRAG" requests are then ignored.

Format:     DRAGMODE  On/Off <current>:

Reference:  Section 6.8 of User Guide.
            Also see the above-mentioned commands.
\DXBIN
The  DXBIN  command loads a .DXB ("drawing interchange binary") file into
an AutoCAD drawing.   These files have a very compact format and are mainly
for internal use by programs such as CAD/camera (tm).

Format:     DXBIN  DXB file:  (filename)

Do not type the .DXB file type; it is assumed.

Reference:  Appendix C of User Guide
\DXFIN
The  DXFIN  command reads a Drawing Interchange File and creates a drawing
from it.  Create a new drawing using Main Menu task 1, and issue the DXFIN
command before drawing anything.

Format:     DXFIN  File name: (name)

Reference:  Appendix C of User Guide.
\DXFOUT
The  DXFOUT  command creates a Drawing Interchange File from the current
drawing.

Format:     DXFOUT  File name: (name)

Reference:  Appendix C of User Guide.
\ELEV
The  ELEV  command is part of 3D Level 1(tm), contained in the ADE-3 package.
It allows you to specify the current Elevation and Extrusion Thickness for
subsequently drawn objects.   The elevation is the Z plane on which an 
object's base is drawn, while its extrusion thickness is its height above 
that base elevation.  Negative thickness extrudes downward.

Format:     ELEV
            New current elevation <current>:  (RETURN or number)
            New current thickness <current>:  (RETURN or number)

Reference:  Section 14.2 of User Guide
\END
The END command exits the Drawing Editor (after saving the updated version of
the current drawing), and returns to the Main Menu.  If you then wish to exit
entirely, select item 0 from the Main Menu.

Format:     END

Reference:  Section 3.2 of User Guide.
\ENDREP
The  ENDREP  command allows you to make a rectangular pattern of the
objects drawn since the last  REPEAT  command.  

Format:     ENDREP  Number of columns:  (integer)
            Number of rows:  (integer)
            Unit cell or column distance:  (value or point)
            Row distance: (value)    OR    Other corner: (point)

See the ARRAY command for another (preferred) method of creating
patterns.

Reference:  Section 5.2 of User Guide.
\ENDSV
The  ENDSV  command is similar to the END command.  Both exit the Drawing
Editor after saving the updated drawing, but ENDSV also saves the vector
file describing the drawing as last displayed on the screen.  The vector
file helps display the initial view of the drawing rapidly the next time 
the drawing is edited.

Format:     ENDSV

If the vector file is not current, it is not saved.  The updated drawing,
however, is always saved.

Reference:  Section 3.2 of User Guide.
\ERASE
The  ERASE  command lets you delete selected entities from the drawing.

Format:     ERASE  Select objects or Window or Last:  (select)

You can easily erase just the last object you drew by responding to
the "Select objects" prompt with "L".  

The  OOPS  command can be used to retrieve the last thing you erased.

Reference:  Section 5.2 of User Guide.
\FILES
The  FILES  command is used to gain access to disk file directories.

Format:     FILES

This invokes the File Utility menu, which displays a list of subtasks.
Using this menu, you can list the names of files on disk, delete
selected files, rename a file, or copy a file to another file.

When listing user-specified files or deleting files, you can use the "*"
and "?" wild-card characters.  "?" matches any character in that position,
and "*" matches all characters up to a period, or to the end of the name.
Thus, "*.*" means all files.

Reference:  Section 3.7 of User Guide
\FILL
The  FILL  command controls whether Solids, Traces, and wide Polylines
are to be solid-filled or just outlined.

Formats:    FILL ON    - Solids, Traces, and wide Polylines filled
            FILL OFF   - Solids, Traces, and wide Polylines outlined

Reference:  Section 6.6 of User Guide.
\FILLET
The  FILLET  command connects two lines, or two segments of a Polyline,
with a smooth arc of specified radius.  If needed, the two lines are first 
extended until they intersect, and then they are trimmed until they meet 
the arc precisely.   If the Polyline option is used, you can apply fillets
to an entire Polyline, or remove the fillets from a Polyline.   FILLET is
an ADE-1 feature, but the Polyline extensions are an ADE-3 feature.

Format:     FILLET  Polyline/Radius/<select two lines>:

   P - Fillet an entire Polyline
   R - Set the fillet radius
            
Reference:  Section 5.2 of User Guide

\TEXTSCR
The  GRAPHSCR  and  TEXTSCR  commands are provided as a convenient means
of selecting either the graphics or text screens from within menus and 
scripts.

Format:     GRAPHSCR   or   TEXTSCR

Reference:  Section 10.3 of User Guide
\GRID
The  GRID  command controls the display of a grid of alignment dots to assist
in the placement of objects in the drawing.

Formats:    GRID ON       - turns grid on with previous spacing
            GRID OFF      - turns grid off
            GRID number   - sets grid spacing in drawing units (zero
                            causes it to equal the Snap resolution)
            GRID numberX  - sets spacing to multiple of Snap resolution

An "Aspect" option is also provided as part of the ADE-2 package.  With it,
you can select a grid with different horizontal and vertical spacing.

Reference:  Section 8.2 of User Guide.
\HATCH
The  HATCH  command is used to crosshatch or pattern-fill an area.
This is an ADE-1 feature.

Format:     HATCH  Pattern (? or name/U,style) <default>:

Styles:     N - Normal                       (BRICK,N  or U,N)
            O - Outermost area only          (BRICK,O  or U,O)
            I - Ignore internal structure    (BRICK,I  or U,I)

If you reply with a standard pattern, a scale and angle for the pattern
are requested.  "?" lists the standard patterns on file, and "U" prompts
you to define a pattern on the fly:

            Angle for crosshatch lines <default>:
            Spacing between lines <default>:
            Double hatch area (Y/N) <default>:

The specified parameters are remembered and are displayed as the defaults
for subsequent HATCH command.  

Reference:  Section 10.2 of User Guide
\HELP
\?
The  HELP  (or "?")  command displays help information.

Formats:    HELP (or ?)
            Command name (RETURN for list):

If you reply with a command name, information about that command is
displayed.  Otherwise, the display consists of a list of valid commands,
and a brief reminder of the methods of point specification.

If the help information does not fit on one screen, AutoCAD will pause
and display:

            Press RETURN for further help.

To continue the help display, press RETURN.  If you want to cancel
the help display, enter CTRL C.

Reference:  Section 3.1 of User Guide.
\HIDE
The  HIDE  command is part of 3D Level 1(tm), contained in the ADE-3 package.
When the VPOINT command is used to generate a 3D visualization, it is in
"wire frame" form; that is, all lines are drawn, even those that would be 
hidden by other objects.   HIDE, which has no parameters, regenerates the
drawing with the "hidden" lines suppressed.

Format:     HIDE

Reference:  Section 14.2 of User Guide
\ID
The  ID  command displays the coordinates of a designated point
in the drawing.

Format:     ID  Point:  (point)

Reference:  Section 5.3 of User Guide.
\INSERT
The  INSERT  command inserts one occurrence of a defined Block into the
current drawing at a designated point, applying scale factors and
rotation.  If the named Block is not defined in the current drawing, but
another drawing exists with that name, a Block Definition is first
created from the other drawing.

Format:     INSERT  Block name (or ?) <default>:
            Insertion point:
            X scale factor <1> / Corner / XYZ:
            Y scale factor (default = X):
            Rotation angle <0>:

The X/Y scales may be specified simultaneously by using the insertion point
as the lower left corner of a box, and a new point as the upper right corner;
just enter the new point in response to the "X scale factor" prompt.  If the
ADE-2 package is present, you can enter "DRAG" to dynamically specify the
insertion point, X/Y scales, and rotation angle.

\
Normally, the Block is inserted as a single entity.  However, if you precede
the Block name with a "*", its individual components are inserted.  In this
case, only one scale factor is requested.

The "XYZ" option on the "X scale factor" prompt is valid only if the ADE-3
package is present.  Entering "XYZ" to that prompt tells AutoCAD that you
want to specify all three scale factors, X, Y, and Z.

Format:     INSERT  Block name (or ?) <default>:
            Insertion point:
            X scale factor <1> / Corner / XYZ:  XYZ
            X scale factor <1> / Corner:
            Y scale factor (default = X):
            Z scale factor (default = X):
            Rotation angle <0>:

Reference:  Section 9.3 of User Guide.
\ISOPLANE
The  ISOPLANE  command permits selection of the current drawing plane
(top, left, or right) when the Isometric snap style (ADE-2 feature)
is in effect.
