ME 6104: Computer-Aided Design

Offered Every Spring


Credit Hours: 3-0-3
Prerequisites: Graduate standing in engineering or related discipline
Catalog Description: Fundamentals of CAD, including geometric and solid modeling, parametric representations, features, and human-machine interactions. Applications to design, analysis, and manufacturing.
Textbooks: Michael E. Mortenson, Geometric Modeling, 2nd Edition, John Wiley, 1997.
Instructors: David Rosen
References: IDEAS Masters Series, Student Guide.
Goals:

After taking this course, the student should be able to:

  • select appropriate geometric modeling techniques for a given mechanical design situation,
  • apply geometric modeling techniques using commercial CAD systems,
  • construct modifiable CAD model of both components and assemblies and use these models in solving design problems,
  • apply geometric tolerances to these models and perform simple tolerance analyses,
  • analyze the appropriateness of virtual and physical rapid prototypes in design situations from an understanding of the information used in their creation.
