Drafting of various geometries using Chamfer, Fillet tool in AutoCad

• AIM:- TO DRAFT CHAMFER AND FILLET TO VARIOUS GEOMETRIES USED IN AUTOCAD.
• INTRODUCTION:-

1. This project is based upon the use of various designs that are used in designing the structures with the use of Chamfer (CHA) and Fillet (F) tools which are used to work with the edges and corners of the structures. These tools give various options to work with the design of the structure, which can make it more attractive, symmetric, and at equilibrium.
2. Use of Line (L), Circle (C), Rectangle (REC) commands.
3. Modifications in Dimension styles from the Dimension tab.
4. Use of Dimension (DIM) command.
5. Use of Trim (TR) and Extend (EX) commands.
6. Use Layers to differentiate between elements of the geometries.
