Choose the format in which the Inventor file is imported:
Choose how the importer treats current scene contents:
For example, say you've created a single object that represents a knob with a threaded shaft and you've applied a black, plastic material to the knob and a silver, metal material to the threaded shaft. If Assign Material IDs is on when you import the model into 3ds Max, the imported faces that have the plastic material are assigned material ID #1 and the faces that have the metal material are assigned material ID #2. If you choose to try different materials while working in 3ds Max, you can quickly make sub-object selections based on the material IDs or apply a Multi/Sub-Object material that contains materials that correspond to the IDs assigned to the faces.
When importing as meshes, this slider lets you determine the degree of refinement applied to the mesh objects. When set to 0 (zero), the geometry is imported as it appears in Autodesk Inventor. When set less than zero, the mesh is optimized with fewer faces, thus reducing detail. If the mesh resolution is set higher than zero, the mesh is tessellated with more faces, providing greater detail.
The Mesh Resolution slider is always set to 0 when you initiate an import.
Left: Mesh Resolution=–7
Center: Mesh Resolution=0
Right: Mesh Resolution=+7
This option determines the model's orientation upon import. You can choose which axis of the Inventor model is vertical.
