Online registration redirects to the SAE International website. (Learn more.)

Providing you have a basic understanding of mechanical drawings, this course teaches how to use engineering drawings that use the International Standards Organization (ISO) standards.

Utilizing the expertise of world-renowned GD&T expert Alex Krulikowski, this course will teach you to recognize what is required on a standard-compliant drawing and recognize geometrical tolerances based on the ISO standards. The course combines information from dozens of ISO standards into a logical understandable topic. Newly acquired learning is reinforced throughout the class with more than 150 practice problems.

Please be aware that this course covers only the topics listed. It does not cover the major ISO principles and terms; view projection; limits and fits; cylindricity; parallelism; position tolerancing MMR; special applications; coaxiality; concentricity; symmetry; general, linear, and angular geometrical tolerances; workpieces edges; or surface texture. See the ISO Geometrical Tolerancing Complete course which covers these topics.

  • What You Receive
  • Learning Objectives
  • Who Should Attend
  • Topical Outline

Each attendee receives a robust collection of learning resources including:

  • Alex Krulikowski’s ISO Geometrical Tolerancing Reference Guide
  • An ISO Geometrical Tolerancing Workbook
  • Class handouts
  • Certificate of Attendance

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.

By attending this class, you will be able to:

  • Explain the structure of GPS and the domains of features
  • Recognize the symbols used in geometrical tolerancing
  • Describe linear size and size conditions
  • Explain the principle of independency and the envelope requirement  
  • Explain geometrical tolerancing concepts: MMR, LMR, RPR, virtual conditions, and collective requirements
  • Describe the datum system (planar datums)
  • Interpret datum target and size datum specifications
  • Interpret the flatness, straightness, roundness, , perpendicularity, and angularity tolerances
  • Explain the fundamental concepts of position tolerances
  • Interpret the circular and total run-out tolerances
  • Interpret the profile any surface and profile any line tolerances

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

Prerequisites
Students should have completed ETI's Engineering Drawing Requirements course or equivalent.
