One of the most common model based digital engineering request is SysML and CAD integration (e.g. LMCO, BAE Systems, Rivia, NIKOLA Motors). This is also comes as great alignment between two disciplines systems and mechanical engineering. In this session, we will present method how to leverage Dassault Systemes solutions to bridge the gap between systems and mechanical engineering for consistent alignment. This presentation will greatly benefit future use cases and Proof of Concepts.
