Geometric dimensioning and tolerancing is the universally accepted method of communicating dimensioning requirements on engineering drawings. This workshop will help you understand and use this universal engineering language to communicate the types and amounts of the inevitable variation that parts are allowed to have, per the drawing.
- Fundamentals of GD&T
- Interpretation & Application of Geometric Tolerances of Form
- Concept of Datums and the
- Datum Reference Frame
- Interpretation & Application of Geometric Tolerances of Orientation
- Interpretation & Application of Geometric Tolerances of Location
- Interpretation & Application of Geometric Tolerances of Profile
- Interpretation & Application of Geometric Tolerances of Runout
Students will be able to:
- Analyze tolerances expressed numerically and calculate minimum and maximum allowable values for dimensions.
- Name the four types of variation that exist on parts, recognize the limitations of numeric tolerances and understand the need for geometric tolerances.
- Understand and apply the symbols used with the geometric system of tolerances.
- Recognize basic dimensions on prints and understand their meaning.
- Identify and properly read feature control frames.
- Recognize when bonus tolerance is available and calculate geometric tolerance values when bonus tolerance applies.
- Create specifications using bonus tolerance where applicable
- Recognize datum feature identifiers applied to features with size and surfaces.
- Identify the datum reference frame including order of precedence.
- Recognize when datum shift is used and calculate the amount of shift.
- Identify and interpret geometric controls on location, orientation, form, profile & runout.
- Construct illustrations of tolerance zones defined by geometric controls, including 3D and 2D tolerance zones, and those allowed to move.
- Properly evaluate inspection data in light of tolerance zones defined by geometric controls.

What former students have said
- "Great class for introduction to GD&T! Followed adult learning model w/ many examples and real life application." - Glen Fantuzzi, Abiomed, 4/24/2013
- "This course was awesome~! I feel like I have the confidence and resources to successfully utilize GD&T" - Hannah Neitzke, Harley-Davidson Motor Company, 10/28/2015
- "GD&T has so many symbols and terminology that as a new engineer can be extremely daunting. This class not only made me comfortable reading prints but also made me comfortable enough to implement GD&T in my future prints. Awesome class!" - Jessica Grabinsky, Smith & Nephew, 10/23/2018
- "Very well put together training from an excellent trainer. Best and most useful course since I started" - Student, Gillette UK Ltd, 2/8/2019
