Model-Based Definition (MBD) is a comprehensive digital approach utilizing 3D CAD models in product design and manufacturing. These models serve as the primary source for Product Manufacturing Information (PMI), detailing the geometry, dimensions, tolerances, and specifications essential for engineering and manufacturing. Key elements of MBD include geometric dimensioning and tolerancing (GD&T), annotations, and assembly information.
