Model-Based Definition

Model-Based Definition (MBD) is a digital approach to creating and managing technical product details. Instead of sharing traditional paper drawings, all information—like dimensions, tolerances, and materials—is embedded directly into a detailed 3D digital model. This allows engineers, manufacturers, and quality teams to access, review, and verify specifications more accurately and efficiently, reducing errors and improving collaboration. Essentially, MBD uses a comprehensive digital model as the single source of truth for all product information, streamlining the design-to-manufacturing process.
