1) TO DRAW THE GIVEN DRAWING BY USING AUTOCAD SOFTWARE

Aim: To create the above geometry

Procedure:

• First the open the software
• Give the command QNEW and press the ENTERE key

• Unit : decimal , precision :0.00
• Angle :decimal degree , precision :0.00
• Angle measure : East
• Angle direction : closkwise
• Area : 20*20
• And finished
• Lets start

Step:1
- create line by command "L" click on the first point( where we want to start) starting point :1,1 then give coordinate 3,0
- Then give the relative coordinate @2.12<45
- then specify next relative coordinate @2.83<135

- so the next coordinate will be @-2,2
- And the next coordinate is @-2,0
- Then click on "close"

Step:2 : Creating circles
- Create an offset of 1 unit from the bottom line of 3 units ie, the centre of circle in y direction
- Enter the command "c" for circle by centre diameter method.
- With" OSNAP -midpoint on "move the mouse on the bottom line of 3 units,then the midpoint 1.5 unit will be snapped.
- Move the mouse vertically towards the above offseted line, so the centre of circle can be located (intersection of the tracked midpoint line and the offseted line)
- Click to specify the centre of circle and give the diameter as 1.2 units

- Similarly, give offset of 2.5 units from the bottom line of 3 units.
- Enter the command "c" for circle (centre- diameter method)
- Specify the centre by "OSNAP on" midpoint and move the mouse towards the line of 2.5 units
