Process :- command line prompt LINE specify first point , type 10,10 then
enter
Line specify next point, write relative coordinate of B point @ 0,40 then enter.
Line specify next point, write relative coordinate of C point @ 40,0 then enter.
Line specify next point, write relative coordinate of D point @ 0,-40 then enter.
Line specify next point, write relative coordinate of A point @ -40,0 then enter.
C. POLAR METHOD:- In the polar method the lines are drawn using angles
and distance.
Open a drafting setting dialog box ,left click dynamic input in pointer input.
Left click on setting changed the mark POLAR format and RELATIVE
coordinate by pointer then OK.
In the auto cad measure of angle from east , then the angle of east is 0d or 360d and measured in anticlockwise direction.
LINE | DISTANCE | ANGLE |
AB | 30 | 90d |
BC | 30 | 0d |
CD | 30 | 270d |
DA | 30 | 180d |
In auto cad type command in line
Line specify first point , left click on A
Line specify next point for line AB write : 30<90d then enter
Line specify next point for line BC write : 30<0d then enter
Line specify next point for line CD write : 30<270d then enter
Line specify next point for line DA write : 30<180d then enter
