Geometric Dimensioning and Tolerancing Training: Level One

Course Description

This one day training course is intended to provide an overview of Geometrical Dimensioning & Tolerancing (GD&T) for people with little or no background in GD&T or technical drawings. The most common tolerance types are shown. The class will consist of a power point presentation with class discussion.  Question and answer sessions will take place during the course to ensure knowledge and understanding has taken place.  Practical examples in block-like prismatic geometry will be featured.

Aims & Objectives

  • Show that GD&T helps insure parts or assemblies will fit together
  • Demonstrate how datums simulate conditions of use
  • Provide an overview of GD&T tolerance types or symbols
  • Work through a few common practical examples
  • Encourage further study outside of class

Benefits to the Learner

  • Understand that datums determine alignment
  • Understand that tolerance zone values are diameters, widths, or thicknesses
  • Recognize the most common GD&T characteristics
  • Identify the difference between the GD&T categories
  • Be able to discuss GD&T with a basic understanding
