Drafting of various geometries using Chamfer, Fillet tool in AutoCad

AIM: Drafting of various geometries using Chamfer, Fillet tool in AutoCad.

INTRODUCTION: AutuCAD Consists of a number of drawing and modification tools. Among the modification tools are the Chamfer, Fillet, Offset, Object Snap, Rotate, Copy , Move, Mirror, Trim, Extend and join.

Chamfer: A Bevel or Chamfer is-

• An Sloped line that meets the End-points of two Straight 2D points.
• A Sloped transition between two surfaces or adjacent faces on a 3D solid.

Fillet: A Round or Fillet is -

• An arc that is created as tangent between 2D objects.
• A curved transition between two surfaces or adjacent faces on a 3D solid.
