Training Course
GD&T to ASME Y14.5 – Fundamentals
An intensive three-day course introducing the fundamental principles of GD&T (Geometrical Dimensioning & Tolerancing) to the ASME Y14.5 standard.
Course Overview
Build Practical Confidence
The course focuses on building a clear understanding of how the ASME Y14.5 standard works, how to interpret the symbolic language of the standards, and how to apply the rules consistently on engineering drawings.
The course incorporates client-supplied drawings in some of the practical exercises to reinforce key concepts and ensure relevance to participants’ own products.
Learning Outcomes
