Procedure
P-1
Step-1:opening to the AutoCAD software and entering the workspace.
Step-2:Setting limits >specify lower-left corner:0,0
Step-3:specify upper-left corner:100,100
Step-4:Set>units>Decimal>intersectional scale>mm
Step-5:Limmax>100,100
Step-6:for Absolute coordinate>right click on the dynamic input icon>select the radio button absolute coordinate and click ok
Step-7:consider the limits(20,0)
- Step-8: line specify the first point(20,5), press enter button,
Step-9:followed steps,specify the next point(40,15),(40,13),(22,13),(22,2),(40,2),(40,0)
Step-10:at the end "c"+enter to close the object after the completion of absolute, we want to change the Absolute to relative Coordinate followed by the Step-6
Step-11:Relative Rectangular coordinate, Specify the line>coordinate>specify the first point (50,0)
Step-12:line specify the next point @(0,15),
Step-13:followed by line specify the next point [@(20,0),@(0,-2),@(-18,0),@(0,-11),@(18,0),@(0,-2)]
Step-14:at the end "c"+enter to close the object
Step-15:Relative polar coordinate,Specify the line>coordinate
Step-16:line specify the first point (50,0)
Step-17:line specify the next point (@(15<90)
Step-18:line specify the next point@(20<0),@(18<180),@(11<270),@(18<0),@(2<90)
Step-19:t the end "c"+enter to close the object
Step-20: Save and close
