Parametric Modeling with I-DEAS 12

Parametric Modeling with I-DEAS 12 is written as a training guide. The text covers I-DEAS 12 and is a hands-on, exercise-intensive look at all the important concepts needed to do feature-based parametric solid modeling. The basic premise of this book is that the more models you create using I-DEAS, the better you learn the software.
