AutoCAD_Drafting images by Coordinate System Methods_Week 1

Aim: To create the geometries from P1 to P2 using all the coordinates system methods and P3,P4,P5,P7,P8,P9,P10 by any one coordinate system method.Also, to draw the profile and the trusses using any coordinate system methods.

Commands Used: Line tool and circle tool.
Note: Use the Imperial Template and the Decimal Units to draft the features. Dimensions are there for
references.

Procedure:
