- Shorten product development by utilizing 3D models to design, simulate, and manufacture complex systems
- Reduce interpretation errors by creating a 3D model that contains complete product definition used by all stakeholders
- Enable collaboration by leveraging a single Product Lifecycle Management system to manage, synchronize, and reuse product development data
