Creation of geometries by Coordinate system methods using AutoCad

YYogendra Meena15 Jun 2021

Aims & Introduction:

Drawing of the given dimensions using various coordinates system is a very basic part of any drawing in AutoCAD. There are different coordinates systems and each coordinate system has respective pros and cons. Using of correct coordinate system for each drawing makes work easier and aesthetic from architectural point of view. A good architecture always makes work smarter and aesthetically good so it meets the exactly the requirements of the client.

In this Exercise, I will be drawing some simple geometrics using the various coordinate system in AutoCAD.

Drawings of P1

Procedure for P1 Drawing Using Absolute Cartesian Coordinate System:

Open a workspace in the AutoCAD
