When will it end? These are some amazing new technologies for you to play with. Stop jerking around with Sketchup and CAD and starting having fun again. This technology was released 2/9/11 so it's hot off the hard drive.
Try form-finding for architectural conceptual design.
Getting StartedAfter downloading and installing Project Nucleus, you may wish to peruse this user manual.
OverviewProject Nucleus integrates the Nucleus simulation engine from Autodesk® Maya® into Autodesk® Revit® and Project Vasari. It allows designers to experiment with "form-finding" in the conceptual design phase by simulating forces directly in Revit and Project Vasari. (An upcoming technology preview of Project Vasari will include the Project Nucleus functionality.)
Project Nucleus can simulate a wide range of physical phenomena in real time, like wind, gravity, constraints, and collisions. These forces can help architects generate free-form shapes, many of which would be impossible to model by hand.
The technology preview ends on December 31, 2011. Any designs that you create remain valid after that date, but the Project Nucleus add-on will no longer operate when the technology preview terminates.
