Abstract
Design changes are frequently encountered in the product development process. The complexity of the design change is multiplied when the product design involves large-scale assemblies with multiple engineering disciplines. Very often, a simple change in one part may propagate to its neighboring parts, therefore affecting the entire product assembly. Both parts and assembly must be regenerated (or rebuilt) for a valid product model. At the same time, the regenerated product model must satisfy the geometric design requirements and meet the designer's expectations. The objectives of the chapter are to (1) introduce fundamental principles of design parameterization for designers to capture design intents at both part and assembly levels, and (2) offer practicing guidelines and illustrations for designers to facilitate the construction of parametric solid models. Note that the guidelines provided in this chapter may be used to support design practice for your project team and can be extended as needed.
