AIM:- Drafting of various geometries using Chamfer, Fillet tool in AutoCad
INTRODUCTION:-
In this project we are using some advance and usefull tools and command which are used for the drafting and editing in the autocad . some of the commands are FIILET, CHAMFER, OFFSET, OBJECT SNAP, POLAR SNAP,LINE, etc
1. DRAWING -1
ANSWER:-
procedure for drafting this drawing are as below;
- Open a autocad sheet , with decimals of a precisoion 0.00
- Make sure ORTHO MODE is ON in this drafting to get presize results
- Then ,type "L" in command line to involk the line command , and specify the first point at 0,0 in XY plane
- Then specify the next point in +x direction of 3 units
- Specify the next point @2.12<45
- Specify the next point @2.83<135
