What is model-based definition (MBD)?

Model-based definition is an approach to creating 3D models so that they effectively contain all the data needed to define a product. With MBD, the model becomes the source authority that drives all engineering activities. This model may further be used downstream by suppliers and across organizations within an enterprise.

Why MBD?

For years, engineers used 2D drawings to deliver product manufacturing information—even as they designed models in 3D. Now, using model-based definition (MBD) methods, engineers embed product data directly in the 3D models, creating a single, reliable source of truth for the whole extended team that prevents errors and saves everybody time.

What the experts say

Model-based definition has a barrier to adoption and it is the tools currently available. Take a look at what else Jennifer Herron, the founder and CEO of Action Engineering and author of the book Re-Use Your CAD: The Model-Based CAD Handbook.2D, had to say.
