 Model-based definition and the application of technical data packages

July 17, 2024

Model-based definition isn’t a new concept. It’s been around for over 10 years.  It’s an incredible tool engineers can utilize in their digital portfolios to help clearly define their designs. 

Siemens has provided MBD and TDP tools in NX and has structured them in such a way that they seamlessly integrate with each other. This article and video will highlight some of these interactions and show how they can provide not only time savings but can help to reduce the opportunity for human errors in the design process. 

  

What is model based definition?

Let’s break down model-based definition – it is the complete digital definition of the design kept inside of the CAD model. It is, if you will, the digital age of 2D drawings. It is used to define important aspects of the design as it’s passed to downstream users. 

MBD was introduced to increase clarity of the overall design intent, to help remove redundancies, and to improve collaboration. Some of the information that can be contained inside the CAD model using MBD are; dimensioning, GD&T information, materials, standards, configurations, quality requirements, and so on.  

Siemens has also provided the tools to tailor the MBD process.  One of the more notable features of the Siemens model-based platform is the logic editor. It provides the opportunity to configure the MBD rules to meet specific requirements.
