Providing you have a basic understanding of mechanical drawings, this course teaches the terms, rules, symbols, and concepts of GD&T as prescribed in the ASME Y14.5M-1994 Standard. Utilizing the expertise of world-renowned GD&T expert Alex Krulikowski, the course offers an in-depth explanation of geometric symbols, including each symbol's requirements, tolerance zones, and limitations. It also includes a comparison of GD&T to coordinate tolerancing; an explanation of tolerance zones; 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 300 practice problems.

  • What You Receive
  • Who Should Attend
  • Learning Objectives
  • Topical Outline
Each attendee receives a robust collection of learning resources including:
  • The Fundamentals of GD&T (ASME Y14.5M-1994) textbook, by Alex Krulikowski
  • A GD&T Ultimate Pocket Guide ('94)
  • A Fundamentals of GD&T Exercise Workbook ('94)
  • Class handouts
  • Official certificate of completion
Tens of thousands of students have learned GD&T through Alex Krulikowski’s textbooks, self-study courses, computer based training, and online learning center. Students who attend courses like this one walk away with more than knowledge. They gain on-the-job skills because the learning materials are performance-based.

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.

Skill Level Needed
Student should have completed ETI's Engineering Drawing Requirements course or equivalent.

By attending this class, you will be able to:

  • Describe engineering drawings: importance, drawing conventions, dimensions and tolerances, standards
  • Explain why geometric tolerancing is superior to coordinate tolerancing
  • 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, cylindricity, perpendicularity, angularity, parallelism, position, concentricity, symmetry, runout, and profile)
  • Describe the datum system
  • Interpret applications of datum targets, feature of size datum specifications (RFS & MMC)
  • Describe the fundamental concepts of tolerance of position
  • Interpret tolerance of position special applications
