Introduction to Model-Based Definition (MBD)

Action Engineering has assembled a series of self-paced, online courses designed to advance the learning and adoption of the Model-Based philosophy across design and manufacturing sectors.

I am Duane Hess, CIO of Action Engineering and instructor for Course 102. This course provides an introduction and orientation to 3D Model-Based Definition (MBD) data sets and the purpose, application, and common practices for 3D Product and Manufacturing Information (PMI). You will also learn how MBD works in conjunction with GD&T and PMI.

Topics that will be covered and what you will learn in the Course 102 seven-part video:

  • What is MBD: How to add MBD and handling data exchange for MBD.
  • Different annotation types for models versus drawings, and best modeling and annotation practices.
  • How MBD is different from drawings, review data exchange, and the definition of a derivative.
  • Techniques to streamline preferred presentation methods, options for annotation authoring, and adherence to standards.
  • A five-step process for adding MBD to a model, and nominal versus mean modeling.
  • Methods to evolve your drawing-based practices into model-based product definition.
  • Learn the basics of Geometric Dimensioning and Tolerancing (GD&T) rules to create 3D technical data sets for effective downstream consumption.
  • Identifying key and product characteristics and how to identify them in the native CAD environment.

Some of the common questions we get from prospective students for Course 102 include:

Q: I don’t see any reference to the CAD software in use at my company. How can I be sure this course is relevant to the work I am doing?
A: The requirements of Model-Based Definition are the same, regardless of the CAD system used, and MBD is CAD-agnostic. Each CAD system certainly has its unique strengths and weaknesses, but that level of detail is covered in other training courses. What is important to your MBD implementation is that everyone at your organization applies annotations (PMI) with consistency. If you are one of those companies that uses more than one CAD system, then this methodology is a must.

Q: We are already using CAD software to design parts and assemblies. I see that this course references GD&T – are there particular GD&T tools or software we should be using to benefit from this course?
A: Each of the large CAD tools have their own GD&T authoring tools for MBD, as well as partner tools. While these tools greatly improve the user experience, they are not necessary for this course, which focuses on the fundamental principles of GD&T, and not so much the usage of the CAD tools.

Q: Would you recommend my team take this course even if other third-party vendors (like our suppliers) aren’t yet ready for MBD?
A: Yes, absolutely. The evolution to Model-Based Definition needs to start somewhere. An understanding of MBD is necessary for all parties who interact with product data, including partners and suppliers outside the company. Wouldn’t you rather be the influencing catalyst directing your standards, processes, and procedures instead of having them defined for you?

Q: Our company has been designing products/parts for many years. Is it too late to start to incorporate MBD?
A: It’s never too late! It also is not always necessary to redo all of your drawings to comply with MBD/MBE practices. It is best to start with a new project to apply MBD/MBE principles. The typical timeline for preparing your enterprise for MBD/MBE is 3 to 5 years that involves people, processes, standards, and tools for engineering, manufacturing, and inspection technology.

Q: Who are the ideal students for this course? What job roles would benefit most from this course?
A: The students from this course should include not only engineering but also any downstream consumer of engineering design documents. This includes but is not limited to manufacturing, quality, inspection, and procurement.

Q: What learning materials are included in this course?
A: The course is delivered online via on-demand video content. Students are provided with access to the content for a set period of time, even after the initial viewing of the course.

Q: Can we combine some of the courses to conduct a webinar with multiple members of our team present? Which courses would you recommend combining in such a multi-day program?
A: We are often asked to bundle our 101, 102, and 108 courses together as a workshop. This set of courses can be delivered as a webinar or in a live classroom setting. These can also be combined with our other courses.

We hope this inspires you to invest in your continuing education by downloading Course 102. If you have any questions on this or any other MBD/MBE courses offered by Action Engineering, please contact us. We hope to see you as one of our online course registrants soon as you begin the journey for successfully implementing MBD and MBE.

  1. Hello,

    I along with two other engineers at my company are looking for GD&T and MBD training. We are a job shop specializing in sheet metal parts. Can you suggest which of your courses would be most beneficial?

    Thank you,
    Nick Carter
