GD&T is an international symbolic language used on mechanical engineering drawings to supplement and optimize traditional coordinate dimensioning and tolerancing.  Dan Bauer from ITR holds Senior GD&T Certification from ASME and will be teaching GD&T Fundamentals including the following:

  • What is it, who uses it, and why
  • Metric and Inch dimensioning and tolerancing conventions
  • Major Elements of GD&T
  • Key elements and major changes to the last three revisions to Y14.5 and ISO 1101
  • Aerospace and automotive specific standards, requirements, and exceptions to Y14.5
  • How to Interpret Feature Control Frames, Datums, and Basic Dimensions
  • Inspection and measurement options and strategies for of each of the 14 GD&T Symbols
  • Advantages and Disadvantages of GD&T for Design, Manufacturing, and Inspection
  • Basic Steps for Applying Coordinate and Geometric Dimensioning and Tolerancing to New Designs or Drawings
  • Customized application and interpretation exercises based on Participant Drawings*


This program is appropriate for all management, design, manufacturing, quality, inspection, purchasing personnel to understand the benefits and proper application and interpretation of GD&T.


*Participants are encouraged to submit drawings (with or without GD&T) to the instructor before and during the seminar for review during the presentation.
