Realistic Visual Style

The Realistic style displays material appearances in editable views. As you rotate the model, the surfaces display as they may appear in various lighting conditions. Select Show Ambient Shadows from the Graphic Display Options dialog to simulate a soft, diffused light. See Changing the Appearance Properties of a Material.

Note: Artificial lighting does not display in Realistic views.
Autodesk Revit

If you are using Autodesk Revit, you can also create a realistic view of the model using Showcase. See Revit Workflows in the Autodesk Building Design Suite.
