M Model-Based Inspection is an important part of a larger trend dubbed Model-Based Definition (MBD), which is sweeping across manufacturing, today. When employing an MBD strategy, the CAD model becomes more than the nominal to which all parts are measured and inspected against. MBD keeps the all-important digital thread intact - from design to manufacturing to inspection and quality reporting. Everything that defines the part exists in a single digital archive, including Geometric Dimensioning and Tolorancing datums. In essence, the archived 3D CAD Model becomes a virtual 'golden part.' Comprehensive deployment of MBD in manufacturing can go far beyond this to include complete Product Lifecycle Management (PLM), but Model-Based Inspection is a great place to start.
