Abstract: This paper describes a computer assisted design process originally developed at the University of Wyoming and now implemented in commercial software. In order to address the need for broadly accessible design rationale, a relatively simple design philosophy has been incorporated in an electronic text book. The text book is organized in three parts: tutorial, design aid, modeler. With the text book loaded on his personal computer, a designer can either read the tutorial like a book or flip to a particular feature design section, such as cross ribs, if he needs to refresh himself on some details. He can then move directly to a specific design tool such as the rib designer which takes into account good design practice, the material to be used and the applied loads to compute geometry required to obtain a particular deflection. The feature design can then be ported to a 3 dimensional modeling package.
