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.
