To be CAD/CAM/CAE/CAI agnostic ensures downstream automation, collaboration across ecosystems, and full transparency & traceability to the authority model. The key goal for MBD is interoperability. The PMI in an MBD CAD would contain any information that is usually conveyed in a 2D drawing, with essential data being semantic: interoperable data read between software & machines, while still being human readable. MBD is the process of annotating a 3D CAD model with product manufacturing information (PMI), aka manufacturing data for building and measuring, to be the single source of authority throughout a product's lifecycle. Recommended pilot projects / process-specfic improvements.What is MBD's relationship to Industry 4.0.MBD improves process efficiency, reduces rework, creates better products with faster time to market, and impacts the bottom line.An MBD approach creates a single source of truth that is used in downstream processes in manufacturing, inspection, and assembly. ![]() Model-Based Definition (MBD) is the process of defining product & engineering data within a 3D CAD model.
