Geometric dimensioning and tolerancing is an international language used on drawings to accurately describe a mechanical part. The language consists of a well-defined set of symbols, rules, definitions, and conventions that can be used to describe the size, form, orientation, and location tolerances of part features. 

Course description:
You will learn the symbols, terminology and rules of Geometric Tolerancing as prescribed in the current standard (ASME Y14.5M-2009). 

Training duration options:

  • 3-days Complete GD&T Class including all topics below.
  • 1 or 2 day custom classes or seminars choosing specific topics and depth of coverage.








Learning Objectives

  • Explain the major default rules found in ASME Y14.5-2009.
  • Explain the tolerance zones for the 14 geometric characteristics.
  • Understand the hierarchy of geometric tolerancing.
  • Recognize proper application of GD&T.
  • Calculate geometric tolerances and boundaries
  • Understand the best approach to take when applying geometric tolerances.
