Anyone who was tuned in to the 'Keynote Address' presentation yesterday from AU will have seen Autodesk CEO Carl Bass introducing a new product to Autodesks ever growing repertoire of design tools. Fusion 360 looks like a fantastic product, branded as '3D CAD in the cloud'. From what I saw of it yesterday in the small introduction, I was blown away. The modeling tools available far exceed the abilities of Revit's native modeling tools.
