Area of Rectangle
Object Allows user to pick an object to calculate
area (circle or polyline).
Add Adds separate areas for a total area calculation
Subtract Subtracts areas from each other.

ID Command 8.5
1. Choose Edit, Inquiry, Locate Point.
or
2. Click the Locate Point Icon from the Inquiry Toolbar.
or
3. Type ID at the command prompt.
Command: ID
4. Pick A point to identity
Point : pick point
Using ID at the corner
of the box rests the
“0,0” origin for relative
coordinates
TIP:
AutoCAD returns the X,Y, and Z coordinates as well as making this the
last point entered in the drawing (to move relative from)
Be sure to use Object Snaps with the ID command.

Drawing Limits 8.7
The drawing limits are two-dimensional points in the World Coordinate
System that represent a lower-left limit and an upper-right limit.
The drawing limits also govern the portion of the drawing covered by the
visible grid and determine the minimum area a ZOOM All displays.
1. Choose Format, Drawing Limits.
or
2. Type LIMITS at the command prompt
Command: LIMITS
3. Type One of the following options
On/Off/Lower left corner <.000,0.000>: 0,0
4. Type One of the following options for the
upper right limit:
Upper right corner <5.0000,2.0000>:36,24
Drawing with lower left limit of 0,0 and upper right limit of
36,24
TIPS:
You can also pick points to define the limits.
The limcheck variable controls whether or not you can draw outside the
limits that are set. A setting of 0 (off) indicates that you can draw outside
the limits and a setting of 1(on) indicates that you cannot.

Plot Scales and Paper Sizes 8.8
The following is an example of setting up an AutoCAD drawing for a D
size sheet of paper (36 x24) with a scale of 1/16=1').
1. Size the object you’re drawing.
2. Border Size 36 x 24 plotted, 576' x 384' drawn.
For some plotters, deduct a 1/2 margin
on top, bottom, and left,and a 1 margin on
the right.
3. Limits Lower left limit 0,0.
Upper right limit 576', 384'.
4. Text Height for 1/8 notes, multiply by 192 which is
the reciprocal of the plot scale.
1/8 plotted, 24” drawn.
5. Hatch Scale for patterns other than architectural.
Hatch Scale = 192
6. Dimension Scale Dimscale = 192
7. Ltscale Ltscale = 96
Determine your object size

AutoCAD 2D Tutorial
Decide Border (Paper) Size
Decide the Scale Factor for Object which is at least 212’, 212’. To do this,
multiply the scale factor x paper size. (i.e.: 1/16”=1’-0’ has scale factor
192)
