Course Descriptions


Do you need to learn how to understand, interpret, or apply GD & T on engineering drawings? If so, this class is for you. Rather than throw concepts at you, we will share concepts with you using industry examples so you feel confident when interacting with and applying the information to your company’s unique applications.

Companies use GD&T to specify how to control the functions of complex designs. If your company is large or small, it is essential to have the ability to communicate geometric tolerances clearly on your prints.

Course content will include:

  • Introduction to Tolerancing (Rectangular/Size Tolerancing and GD&T
  • Form Tolerances
  • Orientation Tolerances
  • Fundamentals of Positional Tolerances
  • Runout and Profile Tolerances
  • Industry Specific Parts and Assembly Analysis
  • numerous examples and illustrations
  • company part analysis
  • Visuals of appropriate gaging and inspection methods
