I’m trying to fit a cylindrical object against a curved wall. Model is easy - section the cylinder with an poly arc representing the wall (or Solid Subtraction or Push/Pull, or Project tool). But I have to manufacture the sectioned sidewall and need a cutting path. Unfold Surface should do this no prob, but yields poly with errors and inconsistencies:
1. Unfolded shape should have one long straight edge opposite an edge with two hills and two valleys. Edge is not straight.
Found a few other things as well that should be corrected, even simple surfaces with holes in them do not create the expected surface. A cylinder wall with a hole sliced in it unfolds to a solid rectangle, without either providing the user with an error (which while annoying, would be "correct" behavior if it isnt going to do it) or creating a surface with any kind of hole in it.
