How MBD is Changing Design Processes

In today’s fast-paced manufacturing industry, the need for increased efficiency, accuracy, and innovation is more significant than ever before.

Yet, for countless years, 2D drawings have been the go-to deliverables for product definition.

These drawings have been used by Engineering, Manufacturing, and other users to communicate design form and fit information required to drive manufacturing processes.

But as we know today, In the realm of engineering and manufacturing, efficiency is paramount.

With the rapid advancement of technology, and the need to shorten product development cycles, 2D drawings have proven to be insufficient in some respects.

The ability to seamlessly communicate design intent and product specifications plays a critical role in achieving customer satisfaction and reducing errors. This is where Model-Based Definition (MBD) comes into the picture.

Unlike 2D models, which can be difficult to interpret and visualize, MBD enables stakeholders to better understand the design intent and product specifications.

With MBD, design iterations become faster and more efficient. Modifying the 3D model allows engineers to evaluate different design possibilities without the need to manually update multiple 2D drawings

Likewise, inherent to 2D models is the potential for errors and misinterpretation during the translation process. MBD eliminates this risk by embedding all the necessary information directly into the 3D CAD model.

Furthermore, traditional 2D models tend to require multiple drawings for comprehensive documentation, which can be time-consuming to create and maintain. MBD eases these processes by consolidating all the relevant information into a single digital model, which in-turn, simplifies the documentation process and makes it easier to update when changes are made.

While the transition to Model-Based Definition may require some initial investment and adjustment, the benefits far outweigh the challenges. MBD streamlines engineering and manufacturing processes, improves collaboration, reduces errors, and enhances overall product quality.

Model-based definition offers a new way of thinking about and creating products.

What is Model Based Definition?

So, what is MBD?

Model-Based Definition is a revolutionary approach to creating 3D models to effectively contain all the data needed to define a product.

MBD defines the source of Product and Manufacturing Information (PMI) as the 3D model (Model-Based) to dictate a product’s features, tolerances, and other critical information.

MBD aims to replace traditional 2D drawings with comprehensive 3D models by incorporating everything into the product definition. This involves attaching all the necessary geometric, dimensional, and other manufacturing information directly to the 3D CAD model, eliminating the need for separate 2D drawings.

As the manufacturing industry moves towards a more digitally connected and efficient future, Model-Based Definition is at the forefront of this revolution, paving the way for more effective product development and manufacturing practices.
