Click OK in the FBX UI window, and your
FBX is imported.
You can download a high
level document that
details FBX 3ds Max Design interoperability.
NoteRevit 2011 FBX files
are fully compatible with only 3ds Max and 3ds Max Design 2011.
When you import Revit 2011 FBX files into 3ds Max 2009 or 2010, lights,
materials, RPCs, and environments are lost; only cameras and geometry are
imported. If you are using Revit 2010/2009 files, use Revit 2011/2010/2009.
