I just saw a link to a rendering with Revit survey on Steve Stafford's blog. http://revitoped.blogspot.com/ This will help Autodesk decide on what rendering engine people want inside Revit. It's only good for 2 more days, May 26
Hold off on installing Revit 9 until this Thursday. Autodesk has found a few bugs and is making a build. They said that they will be complete by sometime on Wednesday, May 3. I'll repost if this date changes.
