Abstract
The design exemplar has been proposed as an approach to developing a CAD query language based upon an analysis of the design exemplar components, vocabulary, and extensions to support logical connectives. Design engineers create models of design artifacts with commercial Computer Aided Design (CAD) solid modeling systems. These systems stop short of providing support for querying and retrieving data from within the CAD data files. The design exemplar data structure and algorithm are offered in this paper as a new tool for interrogation of CAD models. The querying capabilities of a comprehensive commercial CAD system is compared with the querying capabilities of the design exemplar based upon user interaction cues. The results of this comparison indicate that for batch processing of CAD model interrogation, the design exemplar provides, based upon user interaction, a superior and more efficient approach.
