Yeah, the method is not to create additional faces. <G> Seriously though, I'm not sure what you are talking about. Are you asking me if there is a way in AutoCAD to make sure that all the faces have their normals pointing in the same direction? If that's the case, make sure that each face you create has it's vertices created in the same order or I should say orientation, ie clockwise or counter clockwise. If it's a 3dmesh then the issue is moot, since the normals all point in the same direction. OTOH, if it's a PFACE, that is much harder to control. The easiest thing is to assign a 2 sided material to that particular object in 3d Studio. Did that answer your question? If not, I'm sure you'll let me know. <G> Yann Bertaud – VPG, Autodesk.
