Trying to revolve a thin battery case which is a closed sketch but for some reason I get a bad argument when I try to select it… thoughts?
For clarity, I drew the case in section.
Do you select a closed sketch? Can you share a screenshot?
Looks like I need to re-learn copy and paste on iOS too…
So everything is under control? 
Hi - Sometimes it’s hard to select these narrow closed sketches. Please zoom in, and it will work. It gives you the “bad argument” error code, because you have selected one of the lines.
Thanks! … and onward.
