This seems to be a similar problem to the one I had with normals
being reversed on polygons after convertsion to rsd. I've found a
solution!!! Download the demo of AcuTrans 3D from here:

	http://www.unibase.com/~4dsol

it will load DXF/lightwave etc. objects and recalculate the normals!!!
Great program, it's solved all my object problems!

Kev.
