Creation of geometries by Coordinate system methods using AutoCad

AIM - To create the geometries of the given figures using different coordinate systems in Autocad

1. P-1

• Absolute coordinate system: In this the distances are measured from origin.

Procedure:

1. Type the command “L” for line and then give the coordinates for point 1 (2,1) in the command box.
2. Type the next coordinate of point 2 (2,7) in the command box.
3. Type the next coordinate of point 3 (8,7) in the command box.
