ARC
o
r
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

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

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.

"shapes" to be used as commonly used
symbols in the drawing. These are not
typically used in architectural drawings
CONFIG Displays options to allow you to
reconfigure the video display, digitizer,
plotter, and operating parameters.
You should not have to use this
command, since the configuration of
your system has already been done
and you will have no need to change it.

can be transparent
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 Dimensioning sub-command:

ANGULAR 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
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 DINDLI ("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
Draws a pair of crossed lines at
the center of a circle or arc on the
current layer
DIM
CONTINUE
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
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
EXI
T
Exits the dimensioning program
and returns from the Dim:
prompt to the normal Command:
prompt
DIM
HOMETEXT
Restores the text of an associative
dimension to its default (home)
location if you have moved it.
DIM
HORIZONTAL
Draws a horizontal
linear dimension line
DIM
LEADER
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
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
Adjusts the obliquing angle of a
linear associative dimensionsâ
extension lines. Useful in
dimensioning isometric drawings.

DIM
ORDINATE
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
Overrides the dimension variable
settings on a selected dimension.
DIM
RADIU
S
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
REDRAW
Redraws the viewport, just like
the regular REDRAW command.
DIM
RESTORE
Makes a dimension style current
DIM
ROTATE
Draws a linear dimension with the
distance measured origin points,
but with the actual dimension line
set at a different angle.
DIM
SAV
E
Saves the currently set dimension
variables under a dimension style
name for future retrieval through
the RESTORE command.
DIM
STATU
S
Lists all dimension variables with
their current status.

DIM
STYL
E
Switches to a new Text Style
for all future dimensions.
DIM
TEDIT
Allows moving text in associative
dimensions without having to
explode the dimensions.
DIM
TROTATE
Allows rotation of the text of
several associative dimensions at
once.
DIM
UNDO
Undoes any changes made by the
most recent dimensioning
command.
DIM
UPDATE
Changes selected associative
dimensions to use the current
dimension variables, the
current text style, and the
current units setting.
DIM
VARIABLES
Lists the settings of dimension
variables associated with a
particular dimension style.
DIM
VERTICAL
Draws a vertical linear dimension
line

the drawing
EXPLODE Separates a block, dimension or hatch
pattern into its constituent entities or
makes a polyline into a series of
straight lines. In the case of a block that
is exploded, if it was originally drawn on
the 0 layer, it returns to that layer,
regardless of the layer it was inserted
on, and it loses its referential
connection to the original block. In the
case of a dimension or hatch pattern
that has been exploded, their parts go
back to the 0 layer, and are assigned
the logical color (BYBLOCK) regardless
of the layer they were drawn on. In the
case of an exploded polyline, it loses
any width it may have had.

once set by the user, the

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
3DFACE

"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.

3DPOLY
