I modeled a complex flex circuit in sheetmetal, using the "lofted bend" feature along with 3D splines to control the final formed shape. I have to unfold the part to create additional geometry, and I find that when I refold the part, it does not come back to the exact original shape. I am at a loss to figure out why.
I have a attached two versions of the part (one exhibits the problem, one does not, but I don't understand the difference). Also attached is a PPT file explaining the problem. Any help would be appreciated!
