Toyota Motor Corporation adopts Two-CAD Strategy with CATIA V5 from Dassault Systèmes and Creo Parametric (Pro/ENGINEER) from PTC. So it is essential that two CAD systems are well linked and cooperated to each other at every process in product development to successfully and efficiently maximize the capability of each application. To promote this project, Elysium is certified as the solution provider for the capability to translate accurately, especially the complex geometry or assembly structure which are specific to automobiles, while maintaining the interoperability between two CAD systems.
