Parametric Modeling with Autodesk Inventor R8

Text by Randy Shih

Separate editions of this textbook are available. See the bottom of this page for details.

This book contains a series of ten tutorial style lessons designed to introduce Autodesk Inventor, solid modeling, and parametric modeling. It uses a hands-on, exercise-intensive approach to all the import parametric modeling techniques and concepts. The lessons guide the user from constructing basic shapes to building intelligent solid models and creating multi-view drawings.
