Direct Modeling with Pro/ENGINEER Wildfire 2.0

Excerpted from Lesson 10 of Introduction to Pro/ENGINEER Wildfire 2.0.
Published by Schroff Development Corporation, SDC Publications

The following tutorial covers two new and efficient capabilities, using what PTC calls “direct modeling.” The text involves creating parts, an assembly, and drawings, using a set of Pro/E commands that walks you through the process systematically. Instructors will find the text short enough for a one-term Engineering Graphics class at the university level and comprehensive enough for a full in-depth class on Pro/ENGINEER at a technical school or community college. Industry users will find the text valuable for a smooth transition from Pro/E 2001 or Pro/E Wildfire, to Pro/E Wildfire 2.0. Two direct modeling lessons have been included to increase modeling speed and reduce unnecessary menu picks.
