Teaching Three-Dimensional Computer Modeling: Past History and Future Plans

For more than ten years, three-dimensional modeling has been a part of the Graphic Communications Program curriculum at North Carolina State University. Originally taught using a wireframe modeling package on a proprietary microcomputer, 3-D modeling is currently part of both our introductory and advanced CAD courses and includes both wireframe and solids modeling on Unix workstations. Initially 3-D modeling occupied a peripheral role in the curriculum at NC State, but has since evolved into a primary focus. As industry has moved toward the use of integrated 3D product databases in a concurrent design and manufacturing environment, NC State has responded by teaching their students how 3-D product models are developed, documented, and integrated into design and manufacturing, Also discussed is how the instructional approach to 3-D CAD differs from either drafting
