Here is a recent white paper Autodesk released regarding some unique applications of their software for Conceptual Design. The 2009 products that are pending release in the next couple months should prove to be most interesting. Having had access to the Revit Architecture and 3ds MAX Design 2009 betas has been very exciting. I just installed the latest build of MAX Design beta and I'm going to be poking around in that and Revit to see what we can do next. I can't wait to have that NDA lifted so I can tell you and show you all about the goodies to come! Until its lifted, I will have to point you to the press releases Autodesk has published.
