Iam not able to draw line its showing error.Please help me
You have a plane active, why cant you draw a line.
In addition to Tony Cantrell :
Press Esc button then press Ctrl-8 (set orientation normal to sketch plane) and draw any line you need.
is it that you are trying to draw a line on a plane perpendicular to sketch plane? if so you can't.
if you are not sure of the sketch plane, Right click on sketch and select "Normal To" to re-orient your display.
What error are you getting? Also it seems that you're in assembly mode. Further are you making a 3d sketch?
