Autodesk 123D Design

123D is a desktop 3D modeler for Windows. Unlike other 3D programs, you don't need a lot of experience to create high quality objects. It is for people who have always wanted to make cool 3D art but don't have the skills to use complicated (and expensive) software. Created by Autodesk, you'll be able to make 3D designs from scratch. This CAD program has some elements similar to those of other Autodesk software. Tools like edge tweaking, push, pull patterning and symmetry turn your projects into realistic looking models.
