If you see faceted geometry when you import Revit files into 3ds Max using 3ds Max FBX Plug-in, the Smoothing groups option might have been activated. Disable this option to correctly import Revit objects into 3ds Max.
Whenever you import a Revit file using FBX, deactivate the Re-evaluate Smoothing groups option. This option is now deactivated by default in the Autodesk Architectural Preset for all future releases of the 3ds Max FBX Plug-in. In the 2009.3 version of the 3ds Max FBX Plug-in, the Re-evaluate Smoothing Groups option was left activated in error.
The Smoothing groups re-evaluation process potentially slows down the import process, so your import process will speed up (depending upon file size) if you deactivate it. This increase in speed occurs because the importer no longer must evaluate every face in each of the geometries that already has a smoothing group associated with it and then, assigning one or more when required.
