Drafting of various geometries using Chamfer, Fillet tool in AutoCad

AIM: To draw the various geometries using Chamfer, fillet tool in Autocad.

Introduction: One of the most important tool in autocad is the the chamfer and fillet tool which plays a major role in drafting various types of drawings.

The chamfer is a command through which you can cut corners of two adjacent sides of any 2 dimmensional shapes at any distance or any particular angle by entering specific values.

A fillet or round connects two objects with a tangent arc in 2D, or creates a rounded transition between the adjacent faces of a 3D solid. An inside corner is called a fillet and an outside corner is called a round; you can create both using the Fillet command.

4. Select Line tool and draw the lengths starting from base of 1.5000 units,Draw offset at 0.5000. Taking the total length 1.5000 doraw an outer boundary and take offset of 0.5000 for the vertical segments. Follow the steps to draw 2.0000 ht geometry anf rotate towards left. Using Line command draw the L shape geomtrey and connect to make the triagular portion.
