I am learning the sheet meatal modeling. I try to unbend the part and punch a hole, and bend back. But the unbend function is gray. I search the help document but did not find a solution. Need your advice, Thanks a lot.
I worked on this a little bit yesterday, couldn't get the Unbend icon to grey out. It was always available, but I realized today that I didn't try creating unattached walls. Mine were all flat or flange or extruded. Unbend and Unbend All worked as they should. Maybe you could give a little more detail on how you created the walls (you couldn't give less).
