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.

  • 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
  • An 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.

By attending this class, you will be able to:

  • Describe the ISO standards system on technical drawings
  • Recognize ISO drawing practices
  • 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 ISO 286 system of limits and fits
  • Describe the datum system (planar datums)
  • Interpret datum target and size datum specifications
  • Interpret the flatness, straightness, roundness, cylindricity, perpendicularity, angularity, and parallelism tolerances
  • Explain the fundamental concepts of position tolerances
  • Interpret the position tolerance at MMR and special  applications
  • Interpret the coaxiality, concentricity, symmetry, circular and total run-out tolerances
  • Interpret the profile any surface and profile any line tolerances
  • Explain the ISO system for general tolerances
  • Interpret work piece edge specifications
  • Interpret surface texture and surface imperfection requirements

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 completed ETI's Engineering Drawing Requirements course or equivalent.
