NOTE This setting applies only to geometry that is stored as a mesh in the scene. Spline shapes marked as renderable have separate controls for UVW coordinate generation; these are found on the Spline Rendering panel on page 7010. ■ Generate Coordinates For All Objects Automatically generates UVW coordinates for all objects when the drawing is linked. This option tells the File Link Manager to create UVW coordinates, but loading time is increased while the coordinate generation occurs. ■ Generate Coordinates On Demand Does not generate texture coordinates for linked mesh objects. Actively linked objects generate UVW coordinates on demand, so if you assign a material to an object and the material requires texture coordinates, the texture coordinates are silently assigned to that object. If the material or texture map is set to display in viewport, the coordinates are assigned as soon as the material is applied; if not, the coordinates are assigned when the scene is rendered. This option gives you faster loading speed, but no UVW coordinate generation. NOTE Objects in drawings created in AutoCAD Architecture pass texture coordinates explicitly to 3ds Max when you attach the drawing. If you specify on-demand coordinate generation, they might not match the coordinates that were specified in the original drawing. The map scaling is the same, but the texture offsets may be altered. Curve steps For objects such as splines, the number of knot points determines the spline's shape and curvature. The Curve steps value defines the number of segments between knot points. A low value gives you a more linear interpolation between the knot points; a higher number gives you a more accurate curve. Maximum surface deviation for 3D solids Specifies the maximum allowable distance from the 3ds Max surface mesh to the parametric AutoCAD solid surface. Small numbers produce more accurate surfaces with a greater number of faces. Large numbers produce less accurate surfaces with fewer faces. Include group This group allows you to toggle the inclusion of specific parts of a DWG file during the file link process. External references Imports xrefs attached to the DWG file. File Link | 7001
