Model-based definition

Model-based definition

Model-based definition (MBD) is a method of creating 3D models that fully encapsulate all the data required to define a product. With MBD, the model serves as the primary source of truth, guiding all engineering activities. This model can then be utilized by suppliers and shared across different departments within an organization.

For years, engineers relied on 2D drawings to provide product manufacturing information, even while designing in 3D. Now, with model-based definition (MBD) methods, engineers embed product data directly into the 3D models, creating a single, reliable source of truth for the entire team. This approach helps prevent errors and saves time for everyone involved.
