Drafting of various geometries using Chamfer, Fillet tool in AutoCad

CHALLENGE-3

PREPARED BY- MEGHA GUPTA

Drafting of various elements using AutoCAD.

Aim: Aim of the challenge is to understand the basics tools used for the purpose of drafting in AutoCAD.

Introduction: In this project various geometries have been created using various tools like rectangle, polyline, circle, move, offset etc. available in AutoCAD.

As per requirement of the challenge, various drawings showing different element details have been created. Decimal system, architectural system, engineering system has been used for the drafting in this project.
