Bill: I bring .dxf geometry into 3DS from a CAD program called MicroGDS. I find that when I create geometry using a solid modeller there are certain techniques which cause trouble in 3DS. When I punch holes in solids and do many boolean subtraction operations on a solid the resulting mesh may not import at all or I get "Invalid Rat Nest" or "Invalid Mesh Object – Can't Cap" messages all over the place. I have also gotten a "Bright Face" phenomena which may be related to the non-unified normal issue which is also prevalent. Bob
