Creation of geometries by Coordinate system methods using AutoCad

TASK 1:

AIM:

(A) To Create the geometries from P1 to P2 using all the coordinates system methods and P3 to P10 by any one coordinate system

(B) To Draw the profile and the trusses using any coordinate system methods. The dimensions are there for reference.

PROCEDURE:

The Coordinate system methods are

• Absolute Coordinate System,
• Relative Coordinate System,

a) Relative rectangular coordinates,

b) Relative polar coordinates,

• Direct Distance Entry.

Commands used:

• Line command,
• Dimlinear command,
• Text command,
• Circle command.

Starting AutoCAD software:

• Go to START MENU, select AutoCAD 2023
