Creation of geometries by Coordinate system methods using AutoCad

AIM:

• Create the geometries from PI to P2 using all the coordinates system methods. By using the Line tool to create the geometries. use the circle tool in some cases.

SOFTWARE USED:

Autodesk autocad 2021

PROCEDURE:

• first open the autocad software
• give command the software QNEW or go to the application menu and click the NEW option
