The importance of learning gd&t

Whether you are in manufacturing, inspection, or design, there is no way around working with -at least- the fundamentals of gd&t. Having well-designed gd&t training is essential to succeed in your career.  In this online course, We will go over the basics up to intermediate-level concepts. After you attend the course, you will be able to confidently interpret and apply gd&t to engineering drawings.

Who is this training course made for?

Mechanical engineers in general, technicians, manufacturing and inspection, and quality control professionals.

The level of the course

The course is beginner and intermediate level. The course starts from scratch and goes over the basic and intermediate concepts in quite moderate depth. 

Yet it is also highly recommended for you even if you have previous knowledge of gd&t to test the course. 

We strongly believe that achieving mastery in gd&t is essentially achieved through mastering the gd&t basics and fundamentals.

Prerequisites for the course

Basic knowledge of reading technical drawings such as being able to interpret drawing views and projections, and knowledge of size tolerances.

How is the course taught?

This gd&t training is taught through on-demand video lectures rich with animations and graphics that visualize the concepts. The lectures are accompanied by quizzes to continuously check the knowledge. After each section, the learned knowledge will be applied through assignments of a practical hands-on project, after all, the best learning is through doing, there is no exception for learning gd&t.

Which standard is used in the course

The reference standard used in this gd&t training course is the ISO standard. But the course is still equally suitable if you use the  ASME standard. This is because the course focus is not only on how the symbols look but rather going to the meaning behind the symbols. For instance, the measurement methods, the tolerance zones, the common mistakes, and how to use gd&t efficiently to save cost on the design and manufacturing of parts. 

A comparison of the ISO GPS and the ASME Y14.5 makes the gained knowledge transferable between one another.

Easy to follow and stuffed with real-life examples

“I've been a designer for 3 years, mostly working with CAD and calculations, but when it comes to creating drawings, gd&t has always been a pain. I tried to learn from friends and colleagues, but I always immediately got the impression that this subject is really difficult and I can't learn it. There were always discussions and disagreements about what the symbols meant. If you look at the books and reference books on the subject, they like to make things more complicated than they really are, don't they? This course just gets to the point, the instructor is knowledgeable, the explanations are very clear and the course project is very engaging. I look forward to more courses from you”


“This course is for every designer who wants to push his career forward. outstanding experience. I am waiting for more courses from you.”


“So far I am really enjoying the course. The video is professionally made and the instructor is very clear. I am looking forward to the rest of the course.”
