Autodesk Inventor 4

Autodesk Inventor 4 ... Inventor was created to eliminate the limitations imposed by other MCAD software, especially pure parametric, and to capitalize on the process developments now emerging in the manufacturing industry.

With Autodesk Inventor, you'll work efficiently in the context of complete assemblies. In fact, you'll load, view, edit, and save large models two to ten times faster than with other top-selling mechanical design solutions. Autodesk Inventor introduces the concept of adaptive design, a design methodology that enables you to work the way you think, rather than forcing you to adapt to arbitrary processes.
