I'm really not sure what this means for Revit users. It sounds as though we can ( maybe soon ) use 3.5 RPC content ?
My understanding is that Revit currently only supports RPC 2.0 content, not 3.0. The 3.0 content is the more complex '2.5D' and '3.5D' including some terrific cars as well as the animated RPC content.
