Autodesk 123 refers to a family of 3D tools available through various platforms
In 2011, Autodesk first launched the modeling tool, i.e. a end-user friendly Computer-aided design and manufacturing (CAD) software. It was called Autodesk® 123D™ or 123D. As of March 2013, the renamed "123D Design" program still seems to be free. Download is about 450MB and the software probably requires a good 3D accelerator.

Is available either through a web browser or IOS (?)
