Model Based Definition (MBD) is a design approach that uses a 3D model as the single source of truth for all engineering and production activities. It allows the model to drive the manufacture of a part without the need for 2D drawings which can sometimes have errors or be misinterpreted. This can lead to more efficient communication and fewer errors in manufacturing.
Traditional design, relies on 2D drawings to communicate design intent. These drawings can be time-consuming to create and may not provide all the necessary information for manufacturing. They can also be difficult to interpret, leading to errors and delays.
MBD offers several advantages over traditional design. It can eliminate the need for 2D drawings, which saves time and reduce errors. It has the opportunity to provide more information than production drawings, which can improve communication and reduce the likelihood of manufacturing errors. Finally, MBD can be used to create 2D drawings if needed for documentation, but these drawings are generated from the 3D model, which saves time and ensures accuracy.
While MBD offers many benefits, it may not be attainable for all companies. A vertically integrated company can benefit greatly from MBD with all production under one roof. Processes can be implemented internally to make the most of MBD, and questions and comments can be routed back to the designer quicker internally. However, using MBD while working with outside vendors will require work on both parties’ part to integrate a concept through to production. If multiple vendors are involved with their own software platforms, the process becomes all the more challenging.
While traditional design has been the standard for many years, MBD offers significant advantages that should not be overlooked. Companies should carefully consider their specific needs and requirements before deciding which design approach to use. Keene Industries is a top-to-bottom company, being able to concept, design, produce, and test all in one place, making the most of the MBD process from start to finish. This reduces project lead time and identifies defects or errors quicker than traditional methods.
