How about this; Take your BIM model (from Revit or ArchiCAD) and hit print, but instead of a pile of documents being printed, your actual building does!
This may sound ridiculous, but for the guys at http://d-shape.com/ it might soon be a reality. The d-shape is a new type of 3D printer, which unlike all the other 3D printers on the market, it is designed to print large scale. It also uses a low cost sand & glue mix to hold the finished structure together. Think of the possibilities!
