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.
