Here's the problem. I make some parts for a new bumper and for some reason, one of the part can't be put with flat pattern when doing the plan. I do make the part the same way as the other but can't figure why I have problem with that one. I have try to save it unfolded but with no success.
I will post the right and the left part, one work perfectly (TJRBUMPSLM-2P), the other is the problem (TJRBUMPSLM-2D).
