Trouble with Revit import

[prehabitat]

Export to DWG from Revit works fine imo.

The idea of re-authoring is ludicrous, do none of the auto-smooth & group by material options work?

If you don't plan to use any of your clients furniture/etc you can purge/delete it out of the Revit model easily from within Revit: can be a different of about 1/3 smaller (3x Larger) between a cleanly build Revit model and a dirty (Read: Lazy) one.. How big is the revit model, L x W x H of the building (any units) and in MB on disk???

In our office we use RVT->DWG->MAX or most recently have been trying the new Revit Link; which I understood allows a live link to the Revit file from within max - as the production team make changes to the model it is updated in max and groups/etc are preserved in MAX (apparently saves some time on big projects once all the Revit->Max translations are setup ?? not my field): I understand very little about how it works.

For a single snapshot (ie client will never send you any updates) DWG or OBJ might be better (After you've cleaned the Revit Model)

I agree, but it's usually necessary. On the project in question, I ended up biting the bullet and remaking/reassigning materials. I had to guess what material was necessary, since the imported file had 100s (no exaggeration) of multi-subs with no discernible purpose. I ended up looking at the list of object names, selected objects with similar names, then went to the viewport and deselected the ones that clearly needed a different material, and applied my new material. It was probably a couple days of that.

If there's any complexity to the model, of if I know I'm going to be editing any significant portion of it, I remodel from scratch. It's silly that it should be unusable, but it's what nearly everyone I know does as well.
