This paper describes the challenges, solution approaches and recent achievements to provide the translation of parameterized feature-based models between different CAD systems, in terms of the design history of the models concerned. Such procedural models have the advantage of being easy to edit following an exchange, by contrast with the boundary representation (B-Rep) models that can be exchanged using current STEP methodology or similar proprietary solutions, which prove to be difficult or impossible to edit and reuse in the receiving system. Such enhanced CAD translation is necessary in many process chains e.g. engineering collaboration. The use of the described solution has already been demonstrated in the translation of realistic procedural shape models of mechanical parts, and the paper includes a brief description of five industrial application cases conducted in several industries.
