Anyone know a good way to convert out of DXF to a format like 3ds for FLY2 without getting a million polygons which your parts are no longer selected as one peice but now 10. Im using truespace 5Justin

This is what I mean, The picture with less is in DXF and the picture with tons of polygons or whatever you woudl liek to call them is in 3DS. The problem with DXF is ti wont let me render (mesh) it but with only one color. If I name all of my parts and make it a "parent" then it freezes when I load the 3ds. Any idea's??
