Training Course Contents
This goal of this course to help you understand and interpret the fundamentals of GD&T. It is based on the ASME Y14.5-2018.
By definition, GD&T establishes uniform practices for stating and interpreting dimensions, tolerancing, and related requirements for use on engineering drawings and in related documents.
Course Info at a glance
Why take this course
GD&T is essential to ensure functional information and design intent from the assembly to its individual parts. This insures accurate fitting assemblies and spare parts regardless of where they are manufactured.
Designers, toolmakers, inspectors and project managers will greatly benefit from GD&T knowledge.
What the course covers
Our Geometric Dimensioning and Tolerancing course covers the fundamentals and principles of the ASME Y14.5-2018 GD&T standard. The course focuses on the geometric characteristic symbols explaining in detail each symbol, feature control frames, different modifiers and how they affect tolerancing when placed in the feature control frame.
The course also goes into depth on datums and datum reference frames, partial datums and datum target points. You will be exposed to methods of inspection for the characteristics symbols, composite feature control frames and design exercises. The course is delivered with a combination of principles, exercises and drawing examples from an instructor with professional ASME standing and over 20 years of practical experience.

Testimonials
"As a new topic to me it was very easy to pick up and remember. The GD&T Fundamentals course helped me to understand the true function of the part and its relationship to mating surfaces. The instructor was able to carry the course at an excellent speed leaving students enough time to grasp the concept."
— Steven Cargnello, Marsh Brothers Aviation.
"Presented the material in a manner that was east to absorb."
— Paul Bolduc, Bend-All.
"Well organized course, taking it step-by-step. The instructor answered the questions completely and was able to keep the course interesting despite the tough subject."
— Kevin Lowry, TMI.
"The instructor was very knowledgeable and clearly passionate about the subject matter. This will help greatly with checking our purchased parts."
— Alexandre Giles, Multimatic Manufacturing.
"Enthusiastic instructor. Small class, solid training manual. Need GD&T to do my GR&R Studies. Oh and an A+ Coffee Machine!"
— Peter Ngyen, Multimatic Manufacturing.
"My overall knowledge of GD&T has vastly improved. I will be able to look at drawings and fully understand them."
— Jonathan Koot, Exco Engineering.
"Small class made for a pretty thorough learning experience. Very knowledgeable and personable instructor."
— Graham Jokic, XL Tool.
"Very good instructor with expert knowledge, and was able to answer all the questions I had. Good discussions with real world examples. The small class size provides the opportunity for question and answers sessions."
— Warner Wong, L3-Wescam.
"The instructor was from the same background as myself and used examples representative of what is done throughout our workplace. He was confident, comfortable and knew his material. I will be able to create improved prints that indicate/ instruct what is required will reduce re-work and scrapped parts. More accurate and complete prints should reduce assumptions made by the machinists."
— Chris Lishman, Armo-Tool Ltd.
"I liked how GD&T works, and it has very practical applications to communicate fit form and function on drawings. I hope to see this used more at my work to cut down on the hand-written notes we currently use, and aid in our shop floor understanding of what the engineers were thinking as they created the parts."
— Travis Boyd, Armo-Tool Ltd.
