Geometric Dimensioning and Tolerancing

Geometric Dimensioning and Tolerancing (GD&T) is a systematic approach used to define and control the geometry, dimensions, and allowable variations of engineering components. This course introduces participants to the fundamental principles and practical application of GD&T in mechanical design and manufacturing. It explains how geometric controls help achieve accurate, interchangeable, and functional components. Participants learn to interpret engineering drawings and understand GD&T symbols and terminology. The course covers datums, feature control frames, tolerances, and material condition modifiers. It explains form, orientation, location, and profile tolerances with practical examples. Participants also learn how GD&T supports inspection, quality control, and manufacturing processes. The course focuses on applying GD&T concepts to real-world engineering drawings and component designs. It helps engineers reduce ambiguity, manufacturing errors, and unnecessary production costs. By completing the course, participants can confidently read, interpret, and apply GD&T requirements in engineering projects.
