Hey, thanks for the answers everyone! I never really figured out the problem (assuming that there even IS one), but I worked around it by switching to Orthographic when doing close-up work.

I really appreciate your response, but it didn’t answer my questions. Perhaps I was not being clear: I wasn’t asking “What’s a better way to do this?”, I was asking “Why didn’t this work?” I didn’t import as a SketchUp file because I have only the Fundamentals version, and it is not equipped with that function. In any event, even if I had another version that COULD import SketchUp files, I would still want to know why importing the .dwg file did not work – an important functionality, SketchUp notwithstanding. Also, there is the matter of why the ship will display properly in Orthographic but not in Normal Perspective. Still odder, when I render the ship, it is all there, but if I switch back to OpenGL after a rendering, part of the ship will disappear. By the way, I should point out that I have done this same procedure with FAR more complicated SketchUp drawings, and it worked fine. I'm baffled by why it is not working in this case. Does anybody know why this is happening?

I imported a .dwg file of a ship from SketchUp, converted it to 3D polys, and changed some of the colors. It looks fine, but whenever I try to scroll in close, the model starts to disappear. (See attached image.) The odd thing is that is only does this when I’m in a perspective (narrow, normal, wide) viewing mode – it doesn’t happen when it is set to orthographic.
