AIM:

To drafting of various geometrics using chamfer, fillet tool in Auto CAD.

INTRODUCTION:

AutoCAD has numerous drawing and modification tools. Among those below tools are used vast area of drawing.

These are,

Chamfer:

An angled line that meets the end points of two straight 2D points.
A sloped transition between two surfaces or adjacent faces on 3D solid.
The distance and angles that we specify are applied in the order that we select the objects.

Fillet:

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

Offset:

It is used to create concentric circles, parallel lines and parallel curves by selecting objects
We can offset an object at a specified distance or through a point.

Object snap:

OSNAP provide a way specify precise locations, such as end-point, mid-point, center, etc., on objects whenever we are prompted for a point within a command.

Rotate:

This tool helps to rotate objects with respect to specified point.
This happen by entering angle of rotation or zero angle.

Mirror:

It helps to mirror the image we required.
Select the drawing which want to mirror, and use mirror command to create a copy of this object with mirrored position.
