Applications of GD&T

Applications of GD&T is intended for individuals who have previously taken a fundamentals-level course in geometric dimensioning and tolerancing in accordance with the ASME Y14.5 standard.

Participants will learn how to confidently apply GD&T across a wide range of drawings and real-world situations. This course strengthens your Geometric Tolerancing skills, closes knowledge gaps, and helps you reduce product costs through better datum selection and more robust design practices. You’ll also learn how to apply the Tec-Ease GD&T Hierarchy.

Advanced topics—including the use of profile and position tolerances, fixed vs. floating features, proper datum feature selection, and effective tolerance allocation—are covered in depth. The course also expands your understanding of simultaneous requirements, composite tolerancing, profile tolerancing, robust design principles, and boundary calculations.
