Can Unfold but not Fold

Question asked by Kyle Groening on Dec 12, 2019

Making a rolled sheet metal part using a Lofted Bend. One end of the part needs to be slightly larger than the other. The smaller end needs to have tabs to mate with another part.

 

The problem is that when I Unfold the part to make the tabs I cant Fold again. It doesn't matter if I make the tabs or not. Just having an Unfold feature and immediately trying to do a Fold doesn't work. Solidworks gives the error "This part contains features that cannot be unbent."

 

I need to be able to align the mating tabs, so making the tabs after the flat pattern isn't an option. 

 

Any idea what could be causing this problem?
