Sini's Ignite will definitely help on dealing with all data, coming Revit.
If You have it, try Charlie's suggestion.
I wish there were such tool 4-5 years ago when dealt more frequently with Revit models.
Anyway, the problems when such model is imported into 3ds max, is usually due to immense amount of data, splines and probably the biggest culprit - blocks, instanced with their pivot point being common for each instanced object/spline.
Which used to work for me in the past was to put all objects with common material in corresponding layer, and to collapse into single one those with same names.
3ds Max is still way better handling few high poly objects than many smal ones instanced.
Try optimizing the model by getting rid of unnecessary data and collapse similar objects together. This trick usually speeds viewport FPS and any viewport related issues.
