The Autodesk Material Library 2011 provides the appearances for Inventor Fusion.
A graphics card that supports Autodesk Feature level 3_0 or higher is required to render realistic materials. Cards that support Feature level 2_0 (the minimum required to run Inventor Fusion) show low-quality materials that look different from the Realistic Materials. For more information, see the System Requirements.
Alloy steel is the default material for the appearance of objects in Inventor Fusion. You can override the appearance at the component, body, or face level. Changes in appearance of an object, such as from copper to aluminum, do not affect physical properties, such as mass.

Appearance Override priorities
Appearance overrides applied at a component level have the highest priority, and affect the appearance of their children. The second priority is faces, and the last priority is bodies. If a face has an appearance override, changing the appearance of the body does not remove the override. A change to the appearance of the component removes the override.
