If you have tried opening FBX files in Max from a Revit FBX Export, you will have noticed that it did nothing in 3ds Max.
Quick fix (thank you AutoDesk) make sure you have downloaded the latest updates for FBX.

In addition, if you are importing from Revit to Max, make sure your MAX settings are set to feet not millimetres before you import. (If you use Metric settings) This brings in your materials at the correct scale. You can adjust your settings back to millimetres once your file is imported.
