Computer-aided design (CAD) software maker Autodesk is promoting new technology the company has recently acquired by pushing out two new programs -- one of which is currently exclusive to Mac -- that take designs or photographs and help turn them into viable 3D models for either computer use or physical objects. Joining the company's earlier 123D and 123D Sculpt are the new 123D Catch (for Windows) and 123D Make (for OS X), Architosh reports.
