Drafting of various geometries using Chamfer, Fillet tool in AutoCad

Aim : Drafting of various geometries using chamfer, fillet tool in autocad

Introduction :

The autocad is used to draw the various geometry.The line, circle, fillet, mirror etc are used to draw the the given geometry. Chamfer is the command that used to draw the slang edges. fillet is used to draw curved edges.
