I have created a sheet metal box. I go to unbend and all works except for one flange. So I go to Edit Sheet Metal Bend and try to unbend it. and I get the message ' The two sides of the bend are connected'. I am not sure what it really means and mostly, how to fix it, short of deleteing and starting over. Is there some clue as to how it got this way in the first place? I would like to learn how to fix it and how to avoid this as I don't know what I did as the others unfolded properly.
