Not only is ASME’s Y14.5 Standard considered the authoritative guideline for the design language of geometric dimensioning and tolerancing (GD&T); it is essential in ensuring that drawing information and symbols are being interpreted and communicated properly. Establishing uniform practices for stating and interpreting GD&T on engineering drawing and related documents is a critical component of the manufacturing of a part. These good design best practices are directly related to a product’s innovation, beauty and success.

This official ASME course is based on the latest ASME Y14.5-2018 Standard and makes the GD&T concepts easy to learn and apply. By combining lectures with animated graphics and display models, this course aims to ensure that all students are engaged throughout. 

By participating in this course, you will learn how to successfully:

  • Demonstrate a thorough understanding of the fundamental geometric concepts
  • Interpret and explain the application of geometric symbols on drawings 
  • Explain how to select the datum reference frames properly
  • Calculate the position and profile tolerances

Who Should Attend?
Designers, approvers/decision makers, and personnel who need to read and/or interpret engineering drawings and their intent. Staff involved in engineering, designing, drafting, quality control, procurement, tooling, production, purchasing, manufacturing, and CAD inspection.

Course Materials (included in purchase of course):

  • A copy of the 400-page GeoTol Pro 2020 Book and Pocket Guide, by Scott Neumann and Al Neumann, which contains full color graphics and loaded with student exercises. The training materials will serve as a valuable resource long after the training is complete. (Please note that the books are shipped and we cannot guarantee that they will arrive in time for the start of class for late registrants. If your shipping address is outside of the U.S., Canada, or Mexico, we can only provide digital access to the books).

Topics covered in this course include: 

  • Introduction to Geometric Dimensioning and Tolerancing
  • Limits of Size, Rule #1
  • How the Geometric Tolerancing System works (Profile and Position Tolerance)
  • The Datum Reference Frame
  • Product Plans and Position Tolerance Verification
  • Orientation Tolerances (Parallelism, Perpendicularity, Angularity)
  • Case Study ExamplesThis ASME Virtual Classroom course is held live with an instructor on our online learning platform. Certificate of completion will be issued to registrants who successfully attend and complete the course.
