Reusing existing design models and utilizing an e-Catalog for components are required for faster product development. For the acceleration, an e-Catalog should provide parametric computer aided design (CAD) models, since parametric information is necessary for configuration design. There are difficulties, however, in building a parametric library of all the necessary combinations using a CAD system, because there are too many component combinations for each product. To overcome this problem, we propose a table parametric method to generate parametric CAD models automatically, and describe its details.
