This paper describes a STEP data exchange system developed by a program generation method. In the method, data exchange specifications are defined using EXPRESS data description language as a set of STEP data model definition of an Application Protocol, CAD data model definitions of manifold solid B-rep model and the conversion algorithms between the data models. Principal parts of the data exchange system, using CAD data file as input and output, is generated from the EXPRESS definitions with a common data repository. The data exchange system is proved to be applicable easily to each application protocol in a general manner and effective in its exact implementation of STEP, through the data exchange experiments between two commercial CAD systems.
