Creation of geometries by Coordinate system methods using AutoCad

1) Aim : creating the geometries from P1-P2 using all coordinate system and also Line tool to create the geometries

Introduction: In Autocad we have 3 types of co-ordinate systems:

1)Absolute co-ordinate system

2)Relative co-ordinate system

3)Polar co-ordinate system.

1. Absolute co-ordinate system: All Inputs specifying drawing using standard cartesian co-ordinates X & Y.

2.Relative co-ordinate system:After first point enter your next point can be entered by specifying the next coordinate compare /relative from th efirst points. Using relative co-ordinate ,points entered by typing @X,Y and enter.

3. polar co-ordinate system: polar system in auto cadd specifies the distance length at which angle.using polar co-ordinate system,points entered by taping @distance.

commands used :

• Line command
• Circle command
• Text command
