Model-Based Definition (MBD)
Engineering approach where the 3D CAD model itself becomes the source of truth for design intent, requirements, and manufacturing instructions. Replaces traditional 2D drawings.
Why it matters
MBD eliminates ambiguity in design communication and enables downstream systems (CAM, MES) to consume design data directly. Aras integrates with MBD tools like Dassault CATIA.
