Course Description

Bridge the gap between understanding GD&T and using it effectively.

The GD&T Design course bridges the gap between knowing GD&T and using it to design real parts. You’ll learn a structured approach to designing parts that assemble correctly, perform consistently, and clearly communicate intent across design, manufacturing, and inspection.

You’ll learn how to assign datums, dimensions, and tolerances based on how a part actually functions. We’ll walk through practical methods for selecting tolerance values, evaluating worst-case boundaries, and performing part and assembly level tolerance stack up analysis so designs are both functional and manufacturable.


Course Objectives

By the end of this course, participants will be able to:

  • Apply GD&T tools to both new and existing designs.
  • Select appropriate datums and tolerance values with confidence.
  • Perform tolerance calculations and stack up analysis.
  • Defend and communicate your design decisions effectively.
  • Reduce costly design errors and rework through better GD&T application.
  • Design for manufacturability without compromising function.


Who it is for

Those involved in the design/engineering process, including:

  • Design engineers
  • Drafters
  • Product Designers
  • Drawing Checkers

Additionally, this course is designed for those outside of the design process who impact the drawing/tolerances, including:

  • Manufacturing Engineers
  • Inspectors 
  • Machinists who review drawings
  • Tooling and quoting engineers
  • Professionals involved in desing validation


Requirements (Materials and Classes)

  • Participants should have a basic understanding of print reading and must have completed GD&T Fundamentals (or equivalent) as a prerequisite. 
  • Highly recommended but not required to have completed GD&T Advanced
  • Why? Fundamentals and Advanced teach you what the GD&T symbols mean. Design teaches you how to use it.Think of it this way: Fundamentals and Advanced teach you how to use the tools in your toolbox. Design teaches you how to build a house with them.
