Creation of geometries by Coordinate system methods using AutoCad

Aim: To create the geometries by using all the coordinates system methods. By using the Line tool to create the geometries.

Introduction: To create the geometries by using the Imperial Template and the Decimal Units to draft the features. By using the software AutoCAD.

Procedure:

Step:1

• Drawing line in AutoCAD

Ribbon: Home > Draw > Line

Toolbar: Draw > Line

Menu Bar: Draw > Line

Tool Palettes: Draw > Line

Command: Draw > Line

Step:2

coordinates system:

• Absolute coordinate
• Relative coordinate
• Relative rectangular coordinate
• Relative polar coordinate
• Direct distance entry
