Fundamentals of GD&T for Inspectors - Foundational Level ET2053

Topics: Quality, Safety & Maintenance

This 2-day foundational-level course builds on geometric dimensioning and tolerancing fundamentals and teaches an introduction of how to inspect GD&T requirements. 

The course offers an explanation of the geometric symbols, rules, and concepts, the datum system, and how to inspect GD&T requirements using tools from the four categories of inspection tools (CMM; comparison instruments and fixed gages; hand tools and open set up; and production gaging systems).

Each attendee receives: A Fundamentals of GD&T for Inspectors Workbook The Fundamentals of GD&T (ASME Y14.5M-1994) textbook by Alex Krulikowski A GD&T Ultimate Pocket Guide (1994) Class handouts

Newly acquired learning is reinforced throughout the class with numerous practice problems. The scope of the workshop includes how to locate a part for CMM inspection but not how to program the CMM to gather the data point.

Learning Objectives

After completing this class, you will be able to:

  • Describe inspection and engineering drawings
  • Explain key terms used in GD&T and how they affect interpretation and inspection
  • Recognize the modifiers and symbols used in geometric tolerancing
  • Interpret and inspect Rule #1, Rule #2, flatness, straightness, circularity, cylindricity, perpendicularity, angularity, parallelism, concentricity, symmetry, circular and total runout
  • Explain the concepts of basic dimensions, virtual condition, inner and outer boundary and bonus tolerance and their effects on inspection
  • Interpret and simulate planar datums and datum targets for inspection
  • Interpret and inspect feature of size datums RFS and MMC
  • Explain the fundamental concepts of tolerance of position: definitions, conventions, advantages and interpretations and their effects on inspection
  • Interpret and inspect tolerance of position RFS, MMC, and special applications
  • Describe functional gages for tolerance of position (MMC) applications
  • Explain profile tolerancing
  • Interpret and inspect profile of a surface and profile of a line applications

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.


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

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