Tutorial
In this section, you’ll see how the Inventor translator handles materials and material IDs.
Note: You will need Inventor 10 to open the sample files in this tutorial.
From the Turbocharger folder, open Turbocharger.iam.

The components of the turbocharger model have materials applied to them. Two of the components, the compressor and turbine housings, have different materials assigned to individual surfaces, the equivalent of multi sub-object materials within Autodesk VIZ. The translator recognizes these materials and will bring in both materials and material ID’s.
Turn on both Import Inventor Materials and Assign Material IDs.

Click OK to import the assembly.

From the Browse from group of the Material/Map Browser, set the Scene option.

The materials assigned to the scene objects are listed.

The compressor and turbine housings have Multi/Sub-Object materials, while the center section has an Architectural material.
