GD&T to ASME Y14.5 – Advanced

An intensive two-day course in GD&T, which follows on from, and builds upon, the Fundamentals course.

Course Description:

This intensive two-day course develops the more advanced concepts of GD&T to the ASME Y14.5 standard. Participants expand their understanding of datums, material condition modifiers, tolerance interactions, and the deeper rules that govern ASME Y14.5. The course focuses on advanced interpretation and correct application of the standards, with worked examples throughout and opportunities to discuss industry-specific scenarios.

Course Objectives:

By completing this course, participants will:

  • Build on Level 1 knowledge - Reinforce core concepts from Level 1 and extend them into more advanced areas of ASME Y14.5.

  • Master advanced datum structures - Learn how to define datums using complex surfaces, groups of features, contacting features, and situation features.

  • Understand material condition modifiers in depth - Apply Maximum Material Condition (MMC) and Least Material Condition (LMC) correctly — including datum shift, bonus tolerance, and virtual condition boundaries.

  • Interpret complex drawings with confidence - Apply rules for non-rigid parts, projected tolerance zones, multiple feature controls, and grouped tolerances.

  • Gain practical confidence - work on practical exercises with real drawings and parts to gain hands on practical experience.

Who it is for:

This course is designed for individuals who have completed Level 1 and require a deeper, more technical understanding of ASME Y14.5.


The course is particularly valuable for:

  • Design and Mechanical Engineers

  • Inspectors and Inspection Planners

  • Drafters
