Link: Create a Realtime Walkthrough of your Revit Project with Autodesk Showcase
I recently made a tutorial over on the Novedge blog on how to take your slow, chunky architectural Revit model and get it smooth and beautiful for a realtime presentation in Autodesk Showcase that'll make your client ooh and ahh. What's Showcase? Check out the tutorial to find out. I think you'll like it, and you might already have it on your computer if you have a Revit subscription through Autodesk.
