opened both in 2 different softwares and they all open the same as SW, NX8 and SpaceClaim.
Open the proe directly into SW and see what it looks like.
Can you show a picture of the ProE part as it is shaded there.
Try an iges, parasolid (*.X_T), sat and see those work.
I've tried opening the ProE directly in solidworks, but I get the same situation.
I've gone to making flat patterns of the tubes for manufacturing. Thanks for your input.
