Drafting of various geometries using Chamfer, Fillet tool in AutoCad

AIM: To Create Different Constructional Geometries Using Chamfer, Fillet, and other Relative Commands in Autocad.

INTRODUCTION: Chamfer and Fillet are two of the often-used commands used while carrying out civil drafting works. Hence, it is important to know how and when to use these commands as per the requirements of the drawings. The primary function of Fillet is to connect two lines, points, or objects in a certain way in accordance with the structural requirements. You can connect the proposed lines in the form of corners, and also arcs with a certain radius. While Chamfer allows you to deduct the required distance and then connect two points according to the drawing given. So, many other commands in addition to Fillet and Chamfer are used in this challenge to complete the drawings as per the dimensions given in the question.
