Creation of geometries by Coordinate system methods using AutoCad

PParvathi Venugopal12 Jul 2021

Aim: To create the geometries from P1 to P2 using all the coordinates system methods using the line and circle tools.

Introduction: AutoCAD offers three co-ordinate systems in which we make sketches. They are;

Absolute co-ordinate system: Use of cartesian co-ordinate system where all the co-ordinates are with respect to the origin(0,0)
Relative rectangular co-ordinate system: Co-ordinate system in which the co-ordinates are with respect to the previous co-ordinate.
Relative polar co-ordinate system: In Polar co-ordinate system, the co-ordinates whose length and angles are specifies
Direct distance entry

Software used: AutoCAD 2022

Initial procedure: The following set-up should be done before sketching

Open AutoCAD
Type QNEW command in the command box
Set the decimal units
Set the unit
Set the decimal (precision to 0.0)
Set the angle, decimal degree, angle measure, the direction
Set the area as

P1.

Procedure:

ABSOLUTUE CO-ORDINATE SYSTEM:

Type Line command in the command box
Specify the first point (2,1) as the start point
