GD&T (Geometric Dimensioning and Tolerancing) Webinars

Aug 22, 2022 to Aug 24, 2022
Drawing with a bearing


GD&T is an international symbolic language used on mechanical engineering drawings to supplement and optimize traditional coordinate dimensioning and tolerancing. Learn the following:

  • Apply datums, dimensions, and tolerances to new designs and drawings.
  • Select functional datums based on part-to-part interfaces, manufacturing practices, and inspection requirements.
  • Analyze a part within the context of the design to ensure logical dimensional management.
  • Select critical characteristics and specifications based on design requirements.
  • Determine required fits and tolerances between mating parts and features.
  • Select appropriate coordinate and geometric dimensions and tolerances to define size, location, orientation and form requirements.
  • Perform and develop tolerance stacks to select datums and calculate and confirm tolerances.
  • Optimize dimensions and tolerances to improve design fit and function.
  • Correct dimensioning and tolerancing errors on existing designs.
  • Increase part tolerances while ensuring assembly and design requirements are met.
  • Correctly select between and apply position, concentricity, circular runout, or total runout.
  • Select and apply the most common geometric tolerances of form, profile, orientation, location, and runout.

This program is appropriate for all management, design, manufacturing, quality, inspection, purchasing personnel to understand the benefits and proper application and interpretation of GD&T.

Registration includes:

  • PDF participant materials emailed to each participant prior to the webinar
  • Pre/post assessment
  • Various references, GD&T inspection calculators, and other tolerancing tools
  • Certificate of Completion
  • Customized exercises based on participant drawings, views, or examples
  • On-going email and telephone support from ITR available.
