I have a sheet metal part that used to unbend without problems.
A few days later, I have the same file without changes made to it, and it doesn't unbend anymore.
I get the error message " innapropriate edge selected " if I try to unbend it again.
I tried many things, including deleting some of the latest features, and creating the sheet metal part again. Nothing works.
Recreating the whole part from scratch again will be very much work, because it is completely parameter/relation driven.
At the same time as the first part, I created a second part witch has the first part inside it (merge/inheritance) , and has the unbend feature already created. This part still unbends, even when I delete the unbend feature, and add the unbend feature again.
If I try to recreate this file in the exact same way (new file --> merge/inheritance --> create driving surface) it works up until the unbend feature. This will now also fail with the same message (innapropriate edge).
My computer/creo might have crashed between when it used to work and now, I don't remember.
Is there a way to resolve this kind of problems? ( let creo or a tool check for problems inside the file?)
I looked everywhere inside the file, there is no message or hint anywhere that indicates anything wrong.
