Creation of geometries by Coordinate system methods using AutoCad

Aim : Geometry are drawn using the coordinates systems with use of line command and circle.

Introduction :

The Co-ordination systems are classified into

• Absolute co-ordinates
• Relative Co-ordinates
• Direct Distance Entry

Absolute Co-ordination System

The coordinates are consider with respect to the origin.

Relative co-ordinates :

1. Relative Rectangular Coordinates

In this coordinate system the coordinate are used with respect to the last point.

Here first point is specified with respect to the origin. and the second point is specied with respect to last point i.e @8,0

2. Relative Co-ordinates

Here the co-ordinates are given in distance followed by angle.

All drawings are attached below

P1 and P2 are drawn with using the all co-ordinates system.
