NOTE This switch presents several modeling concerns that you should be aware of: ■ Material assignments from ADT are not translated during the import process.. ■ If you want to assign materials to these objects, use Multi/Sub-Object materials. The assigned material IDs match the color indices specified in ADT (red=1, white=7, etc.). ■ Depending on the Texture Mapping option you choose, UVW coordinates are translated correctly. Use scene material definitions When on, 3ds Max checks the current scene for any currently used materials with the exact same name as a material name in the incoming DWG file. If a match is found, the importer does not translate the drawing's material, but instead uses the material defined in the scene. When off, the File Link Manager always uses the material definitions contained in the DWG file, and will overwrite scene materials with the same name, regardless of which objects the material is applied to. All material definitions stored in the DWG file are reloaded (even when using a selective reload). If you make changes to a linked material, in Autodesk VIZ, then reload, those changes will be lost (if the switch is off). Geometry Options group Weld nearby vertices Sets whether coincident vertices of converted objects are welded, according to the Weld Threshold setting. Welding smoothes across seams and unifies normals of objects with coincident vertices. Weld threshold Sets the distance that determines whether vertices are coincident. If the distance between two vertices is less than or equal to the Weld Threshold, the vertices are welded together. Auto-smooth adjacent faces Assigns smoothing groups on page 8130 according to the Smooth Angle value. Smoothing groups determine whether faces on an object render as a smooth surface or display a seam at their edges, creating a faceted appearance. Smooth-angle Controls whether smoothing occurs between two adjacent faces. If the angle between the two face normals is less than or equal to the smooth angle, the faces are smoothed. Orient normals of adjacent faces consistently Analyzes the face normals of each object and flips normals to make their directions consistent. If the AutoCAD (DWG) Files | 7193
