An Architecture for Universal CAD Data Exchange

Ari Rappoport

Parametric feature-based CAD data exchange is one of the most important open problems in solid modeling. The problem is significant and challenging both scientifically and commercially. In this paper we present a very general outline of the Universal Product Representation (UPR) architecture, which provides universal support for all data levels employed by today's CAD systems. The architecture has been implemented with successful results.
