As collaborative design and configuration design gain increasing importance in product
development, it becomes essential to exchange parametric CAD models among participants. Parametric
CAD models can be represented and exchanged in the form of a macro file or a part file that contains the
modeling history of a product. The modeling history of a parametric CAD model contains feature
specifications and each feature has selection information that records the name of the referenced
topological entities. Translating this selection information requires solving the problems of how to
identify the referenced topological entities of a feature (persistent naming problem) and how to convert
the selection information into the format of the receiving CAD system (naming mapping problem). The
present paper introduces the problem of exchanging parametric CAD models and proposes a solution to
naming mapping.
