Drafting of various geometries using Chamfer, Fillet tool in AutoCad
AIM : Drafting of various geometries using Chamfer, Fillet tool in AutoCad.
Answer : First i will explain what is Chamfer and Fillet in AutoCad
Fillet: is a tool in AutoCad which is used for rounding corners of any object as per requirement in drawing.
It is required when object dosent have sharp edges in that case we can use Fillet tool for roundning the corners.
Chamfer : Chamfer is another tool in AutoCad which is used to provide sloped or angled edges of any object.
Now i will draw each drawings as mentioned in attachment by using Chamfer and Fillet tool.
1.) Here is the first drawing.
