Model-Based Definition (MBD)
Model-Based Definition (MBD) is the engineering practice of embedding all manufacturing, inspection, and product definition information directly in a 3D CAD model—replacing 2D drawings as the authoritative design artifact and making design data machine-readable for downstream processes.
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.
