Tinkercad - Solid modeling for artists and makers

Autodesk Releases Free App That Brings 3-D Printing To The Masses [Video] | Co.Design If you hear "maker culture" and instantly think of grease-stained weirdos who drone on about steampunk and "screws not glue"... well, you wouldn't be wrong. But when a giant software company like Autodesk throws its weight behind "makers," you know it's much more than a subculture. "There was this huge digital content generation that emerged, but now that 'Generation C' is turning into 'M,' the Make generation," Tatjana Dzambazova, Senior Product Manager at Autodesk, tells Co.Design. 123D lets you easily fabricate objects, not just visualize them. 123D differs from other free 3-D modeling software like Google Sketchup in that it's designed to let you easily fabricate objects, not just visualize them. Because 123D has physical output in mind, it includes ingenious features like a "shell" command that turns any solid digital model hollow, which makes it much faster and cheaper print. Autodesk intends 123D to be simple enough to play with like a toy. [Download 123D for free here]
