hehe, I use ProD for some pretty good looking models.
Let me look right now, I've never considered using it for DB (and I definately would advise against it, I will explain in a moment)
OK, stand alone ProD is NOT compatible with DB simply because it cannot make .x objects. You would have to export to vmrl then import that into another program, like 3ds max, and export that to .x. BUT, you SHOULD NOT use ProD because it does not export mapping coordinants. No CAD programs do. This means that when you try to texture your object, well, you wont be able to. It will totally screw up the texture. And even if you dont texture it, the lighting on your object in DB will be VERY bad, ranging from all black to just one color. Personally I use 3ds max at my school for making objects, since I dont want to pirate it at home...
