CAD Data Exchange Using the Macro-Parametrics Approach: An Error Report

CAD data exchange is vital to industrial engineering innovation. Because companies use different CAD systems, and there are collaborations between these companies, CAD data exchange is essential to complete the whole design process. Because the current ISO10303 (STEP) does not provide a mechanism to exchange parametric information among CAD systems, we are trying to solve this problem based on the Macro-Parametrics Approach (MPA). The entire implementation is based on TransCAD, which bridges different CAD systems. Translators of famous CAD systems are also implemented based on TransCAD. In this paper, test rallies among those translators and errors which are found during the test rallies with a simple CAD model are summarized and analyzed.
