Fundamentals of GD&T ASME Y14.5M 1994 - Foundational Level ET2401

Topics: Quality, Safety & Maintenance

The 2-day foundational-level Fundamentals of GD&T course teaches the terms, rules, symbols, and concepts of geometric dimensioning and tolerancing as prescribed in the ASME Y14.5M-1994 Standard.

The class offers an explanation of geometric symbols, including each symbol’s requirements, tolerance zones, and limitations. It compares GD&T to coordinate tolerancing, Rules #1 and #2; form and orientation controls; tolerance of position; runout and profile controls. Newly acquired learning is reinforced throughout the class with more than 100 practice problems using industrial drawings.

Each participant receives: The Fundamentals of GD&T (ASME Y14.5M-1994) textbook by Alex Krulikowski, a GD&T Ultimate Pocket Guide (1994), a GD&T Workbook with Engineering Drawings (1994)

For more in-depth GD&T coverage, see our 3-day Fundamentals of GD&T advanced-level course, which covers everything from this 2-day course, plus these additional topics: drawing standards, using tolerances on CAD models, position tolerance special applications and calculations, related and unrelated actual mating envelope, fixed and floating fastener formulas, and geometric tolerance inspection methods. It also includes 50 additional practice problems using industrial drawings.

Learning Objectives

By attending this course, you will be able to: 

  • Describe what dimensioning and tolerancing is
  • Describe the key terms used in geometric tolerancing
  • Recognize the modifiers and symbols used in GD&T
  • Explain the rules used in GD&T
  • Describe the concepts of basic dimensions, worst-case boundary, virtual condition, inner and outer boundary, and bonus tolerance
  • Interpret the various types of tolerances (flatness, straightness, circularity, perpendicularity, parallelism, position, runout, and profile)
  • Describe the datum system
  • Interpret applications of datum targets, feature of size datum specifications (RFS & MMC)

Who Should Attend

This course is valuable for individuals who create or interpret engineering drawings, product and gage designers; process, product, and manufacturing engineers; supplier quality engineers/professionals; CMM operators; buyers/purchasers; checkers; inspectors; technicians; and sales engineers/professionals.


Participants should have basic knowledge and command of the  GD&T ASME Y14.5  standard, which provides guidelines for engineering drawing sheet layout.

You must complete all course contact hours and successfully pass the learning assessment to obtain CEUs.
