Revit - Impression - Photoshop - Revit

Doing an interesting roundtrip today:

1. Export Revit floor plan to DWG - basic walls / doors / floors only
2. Add floor finishes / landscape / people / vehicles in Impression
3. Save PDF, open in Photoshop
4. Add extra Entourage (furniture etc) and text in Photoshop
5. Save for Web and re-import into Revit.  Scale to match floor plan from step 1.

It may sound like a pain, but its working quite nicely...
