Advanced Geometric Dimensioning & Tolerancing

Event Start Date:

March 14, 2024

Event Start Time:

8:30 AM

Event Location:

Manufacturers Resource Center

This Advanced Geometric Dimensioning & Tolerancing (GD&T) workshop is for those with some previous exposure to geometric dimensioning and tolerancing.

In this two-part workshop, Part 1 will be a review of the GD&T symbols and rules. In Part 2 more advanced topics are covered, including an update about the revised Y14.5-2018 standard. We’ll also discuss the proper application of tolerances for designers, including a short module using a tolerance stack spreadsheet.


  • Learn the less-common GD&T tools: translation, datum shift, resultant condition, all over boundary
  • Determine which datum features to choose based on function
  • Select proper GD&T symbols for a mock design
  • Perform tolerance stack calculations for both plus/minus and geometric tolerances
  • Review of GD&T standard (2018 vs. 2009 versions)
  • Datums at virtual condition (the MMB modifier)
  • How to choose MMC, RFS, or LMC
  • Tolerance stack analysis using the “loop” method


Geometric Dimensioning & Tolerance Fundamentals or basic knowledge of GD&T.

Who Should Attend

Process Engineers, Product Engineers, Quality Engineers, Quality Technicians and Quality Managers.
