Avoid Classic Mistakes When Implementing MBD

Can you recall an instance where spending more time on project setup would have saved time (and money) over the life of the project? Time invested upfront, more often than not, makes up for itself later. Model Based Definition (MBD) implementation is no different!

Norm Crawford of Crawford Dimensional Management will discuss classic MBD implementation mistakes, and provide real-life examples of the related benefits that can be achieved, at the Collaboration and Interoperability Congress (CIC) in Washington, DC on October 29, 2015.

Presentation Title: Classic Mistakes in MBD – How They Can Impact Early Benefits


  • Implementing MBD correctly
  • Mistakes to avoid
  • Benefits to be realized


When implementing Model Based Definition, people often try to simply import tolerance information from the 2D drawing format to the 3D model. However, to gain early benefits from the model based enterprise process and to avoid losing downstream benefits, classic mistakes need to be avoided. In this presentation, Norm Crawford will discuss these implementation mistakes and provide some examples of the related benefits that can be achieved.
