Q.1 Aim - Drafting various geometries using AutoCAD commands.

Introduction - Drew given geometry by using line and circle command.

Procedure -

1. open AutoCAD

2. set the units to decimal

3.By using line command first draw 3.00 line

4.then by using polar snapping 45,90,135.. draw the inclined line 2.12 length

5. after that by polar snapping draw next lnclined line of 2.83 length

6. draw horizontal line of 2.00

7. the close the line to the first point . the outline is complete

8. to draw circles first mark circles by points by using relative co-ordinate system

9. draw the circle of required diameter by keeping centre of the circle maked by the point
