ASME Geometric Dimensioning and Tolerancing (GD&T) Online Course Collection

GD&T is an essential tool for communicating design intent. Learn the skills needed to interpret engineering designs and avoid mistakes that occur during the manufacturing process with ASME’s official GD&T online courses.

Fundamentals of Engineering Drawings and GD&T

Our self-study online courses introduce the essentials skills to read, interpret, and understand manufacturing intent through the lens of ASME Y14.5—the authoritative guideline for stating and interpreting GD&T.

GD&T Symbols and Controls

In GD&T, each feature of a manufactured part is specified by datums and controls. Our GD&T Guided Study courses enhance your skills related to choosing datums and feature controls, per ASME Y14.5, through drawing assignments, quizzes, and email Q&A with an expert instructor. Courses can be completed at your own pace within a 6-week session.

GD&T Best Practices, Tolerance Stacks, and Applications

Join a live GD&T Virtual Classroom course to learn directly from an expert instructor and go beyond the basics. Review critical geometric theories, calculate position and profile tolerances, and perform advanced tolerance stacks through a series of case study problems. ASME Virtual Classroom courses are live, scheduled classes with an instructor in an online environment.
