It sounds like the model was not biuilt correctly for a polygon renderer (the MOST common problem in not getting models in properly to 3DS via DXF). If your model is composed extensively of individual entities (3D Faces or Lines with thickness) then you are probably experiencing this problem. There is one golden rule when constructing such entities in _any_ program: every face that's adjacent to another face (that is of the same mesh) must share two vertices with it. If this does not occur, and only one vertex is shared, then the face normal is going to be erratic. While it may be too late to correctly model this pproject, keep it in mind for your next. Until then, you'll have to resort to rendering a LOT more faces by using the 2-Sided opotion as Robert suggested. Remember, don't try using Boolean operations or SXP materials on this model since they will not work correctly. – Phil p.s.
