revit export fbx with materials

That's fine. My complete (intended) statement should read: Now that we have a 3D custom exporter at our disposal, it is easier and more effective to use that to implement OBJ export rather than traversing the entire database, reading the geometry from each element, and trying to interpret how it should be represented in a specific view.
