Creation of geometries by Coordinate system methods using AutoCad

• Aim:

• To create a geometries from p1 to p2 using all the coordinate systems which are as follows:-
• Absolute coordinate,Relative rectangular coordinate,Relative polar coordinates system

• Introduction

• Click Autocad icon from desktop (here i am using Autocad 2023 version)
• Then, before staring new drawing work, we have to set up some instructions which are follwing:
• click on Application menu
• next,click on NEW
• next,click on Create New,
• here, set the limits and units (imperal templetes ,decimal)
• Dynamic input button should be OFF,ON orthogonal mode

• Procedure
