<< My problem is the age old one of having faces missing or reversed>> There are a couple of tools on the 3D Studio side that might help you with your existing models, for example Yost's OPTIMIZE routine. However the best remedy is to create your models in AutoCAD with the knowledge they are going to 3D Studio. The most important rule to remeber is that for any two adjacent faces on the 3D surface of your AutoCAD model, they must share two vertex points. Otherwise, they will be treated as different surfaces. If they are treated as different surfaces, you might see a seam and the normals might not be pointing in the same direction. If you folow the fule of adjacent faces sharing two vertex points, the whole object will be one surface, and all the normals will be facing the same way. It might be the wrong way, but since the normals are unified, a simple Object Normals Flip will give you a proper object. -brian
