modeling = logical data synthesis representation
more than just graphics ... any data IN to the BIM model:
3D, 4D=Time, 5D=$, 6D=ADA, 7D=Sustainability, 8D=Maintainability, 9D=Acoustics, 10D=Security, 11D=Heat ... nD
ongoing project example:
Members in our ranks are currently in talks/training w/ITW Americad to become the NorthEast partner/implementor for VisionRez (an add-on to AutoCAD Architecture). Industry pundit Lachmi Khemlani has stated VisionRez "is one of the best examples of a likely future technological trend in AEC: BIM applications customized for specific building types [in this case houses] with many smarts and rules specific to that type built in".
