If you’re an engineer or designer, you’ve probably already heard about model-based definition (MBD), the practice of adding non-geometric engineering information to a 3D model. Traditionally, that data has been found on a 2D drawing.
Intuitively, it makes sense to keep everything in one place. After all, you attach files to an email so recipients can easily reference connected/relevant information. Or, you create folders on your desktop to keep project files neat and tidy.
But, are the benefits of using a 3D model as the single-source of design information worth the effort of changing the way an enterprise has been doing things for a very long time? Maybe decades?
Let’s hear from someone who has gone through the process of implementing MBD in their organization. Recently, I asked Curtis Brown to share his perspective about MBD and where to start.
Brown has a lot of insight to share about the switch to MBD. He is a principal engineer at a multinational company. He’s helping his team create trusted product models that others can confidently reuse throughout the enterprise. Here’s what he said about the process of switching to MBD:
Ramesh: What is Model-Based Definition (MBD)? What is Model-Based Enterprise?
Brown: MBD is the 3D annotated model and its associated data elements that fully defines the product in a manner that can be communicated and used effectively by all downstream customers without a 2D drawing graphic sheet. Model-Based Enterprise (MBE) starts with an authorized trusted MBD.
MBE is an organization that successfully reuses MBD. Put another way, MBE is a fully integrated and collaborative environment founded on 3D MBD data that’s validated, authorized and shared across the enterprise to enable the realization of products from concept through sustainment.
Ramesh: Who benefits most from an MBD approach?
Brown: Major benefits of the MBD model are seen by downstream organizations, such as:
Ramesh: Is it difficult to switch to MBD?
Brown: The psychological aversion to change from 70+ years’ worth of 2D static drawing-based business must be overcome. Some specific business barriers that must be addressed include:
Ramesh: If a company wants to start using MBD, where should they focus?
Brown: MBE starts with a trusted MBD process. So…
Ramesh: How does a company implement MBD?
Brown: Here are my thoughts, you do MBD to do MBE. So:
Ramesh: How do you measure the success of MBD?
Brown: Measure against –
Ramesh: Any final comments?
Brown: To summarize, MBD is to:
With the goal of delivering…
2D drawings are more prone to interpretation errors. And they’re more likely to result in data inaccuracies. If your organization is running into these issues, it’s time to consider whether you’d benefit from an MBD approach.
