Abstract
In embodiment and detailed design, one is often concerned with sizing and geometric arrangement, i.e. determining the values of key parameters, dimensions, and locations of design elements. Feasible designs need to satisfy certain relationships between these parameters and entities. “Design Exemplars” are introduced as a concept for describing complex situational patterns and extracting information of interest from enhanced CAD models. Such a canonical representation of parametric problems is needed for bridging the gap between CAD and geometric reasoning used in AI. This paper will show that there are a large number of generic parametric and geometric problems that transcend domain boundaries. In design and manufacturing automation systems, these problems have typically been addressed in domain specific terms; lacking on the one hand, a uniform characterization, and on the other, a unified solution methodology.Key wordsEmbodiment DesignCase Based ReasoningExemplars
