I hope you can help. I'm attempting to accurately model some of our foldable parts using the Sheet Metal feature, in such a way that we can anticipate any problems with interferences before manufacturing. I've managed to get a good start on how to work around the feature such that it allows me to have material thickness with V-Groove cuts and still be able to fold the part (thanks to the post by Bernie Daraz in Accommodating V-cut and Press Brake in Solidworks). As such, I have no issue with simple parts that require folds in only one direction, ie. boxes.
However, when I get to more complex folding patterns, I cannot seem to get all the folds to work correctly. It works just fine when it's a single thickness profile:
But when I add the thickness with the V-Grooves in, using the exact same method as the boxes, I can only get it to fold around 1 axis at a time.
If I make the folds in one direction, any of the folds in the other axis simply refuse to work. I do not know if is an interference issue, a bending radius issue or anything, the error when I try to do the bending line gives no hints. I'm relatively new to using Sheet Metal and I can't tell if there are any fundamental physics rules in the tool I might be ignorant of that cause the bends not to work. Any suggestions?
*I've attached both the single thickness file ("test") and the part with the grooves if it will help.
