1. GD&T Basics Online Training Course – Fundamentals

Duration: Self-paced, 35+ lessons.
Level: Entry-level to Beginners
Medium: Online only 

When it comes to geometric dimensioning and tolerancing training courses, GT&TBasics is known for being a reliable course provider. 

You don’t need to have any prior experience as a machinist to take this course. 

The range of online courses available are more than enough to help you understand all 14 GD&T symbols and create datum reference frames by the time you are finished. 

The course starts with a simple CAD training session that eventually helps you understand the design intent of various projects and products. 

It is important to note that this is just a fundamentals course and won’t turn you into an expert. Instead by the 8-10 lesson-mark, you will find yourself to be able to identify elements, make informed decision, and incorporate elements into real world. 

The course allows the option of crafting a custom GD&T training course, in which you select whether you want to learn in a boot-camp-like structure, self-paced (for those who have a busy schedule), or go full professional by treating it as academia. 

This training course is a definite recommendation for engineering hopefuls in 2021, considering how it prepares you for the next, more advance courses. 


The basic course should generally cost you $399, but as at the time of writing there is a promotion going on (till July 1st 2021), in which the course costs you $299.

2. GD&T Basics Online Training Course – Drawing

Duration: Variable, 25+ lessons.
Level: Entry-level
Medium: Online only

Another entry from GT&TBasics is the Drawing course which focuses on helping you understand and create impeccable models from scratch in regards to your query. 

You will begin with simple engineering structures and then move on to more complex structures. 

The course doesn’t have any prerequisites such as experience or even an engineering background. You start from the ground-up and learn all you need to know about GD&T machining, product design, and more. 

We recommend this training program to all students who are looking to one day become GD&T professionals and be well-known for their engineering drawing skills in any given organization. 


Again, this course is very flexible and allows you to make your own course – or you can go with the pre-made options as well. The course will cost you $199 normally, but there is an ongoing promotion in which the course costs just $149.

3. GD&T Basics Online Training Course – Advanced Training Course

Duration: Self-paced, 30+ lessons.
Level: Advanced
Medium: Online only

The pinnacle of online GD&T online training programs, this advanced course is dedicated to engineers who want to perfect their craft and make a career out of product design and want a prestigious certification to attach with their resume. 

While the material itself is presented in a very digestible manner (ASME certification guide, real world application concepts, tolerance calculations, and more), you will find that the concepts within are complex and demand your attention throughout the course. 

There aren’t many courses out there that cover everything – from GD&T fundamentals all the way to every minute modifier that you could have to deal with. 

The only issue we found with this course and the two associated training programs reviewed above is that while you get an online 100% completion certificate with all three, there is no test at the end to truly test your concepts of GD&T. 

However, the good news is you can simply give yourself an assignment from the internet and test your skill level on your own. 


The advanced course is one of the most expensive ones offered by GD&T Basics, costing $499 normally but in the ongoing promotion, it costs $399.

6. GeoTol – GD&T Fundamentals Program

Graphical user interface, application

Description automatically generated

Duration: 40 hours
Level: Beginner
Medium: Online & On-Site (Before COVID)

GeoTol GDTP training course has been an industry leader since 1983 when it comes to helping students and engineers build a strong foundation with the fundamentals of GD&T. 

The training program offers a plethora of knowledge to prepare individuals for becoming GD&T professionals, which students get to use to their liking. 

The program is based on ASME Y14.5-2009 standards, which is why it isn’t higher in our list. This basically means that the course might be slightly outdated. However, when going through the material itself, we found that the difference isn’t that dire. 

We found this program to be exceptionally in helping more advanced, tricky areas of tolerance training.


The course will set you back $299, which is an acceptable price point in our opinion. We wouldn’t think twice before recommending this option to students.

7. Udemy Geometric Dimensioning and Tolerancing (GD&T) Courses

Duration: Variable
Level: Beginner to Expert
Medium: Online only

Udemy offers a myriad of different GD&T training courses that are geared towards helping a complete layman start learning about the basics of Tolerance and dimensioning.

 If you take these courses, especially the GD&T Basics and GD&T Advanced, you will have covered virtually every concept you might need to know about. After that, additional courses will only help you fine-tune what you already know, polish your skills and potentially be the best anyone has ever seen. 

These ASME and ISO standard compliant, and will help you on your road to becoming an expert product designer. 

However, there is one small hitch that you need to keep in mind. Udemy courses aren’t exactly widely accepted and are not considered to be a valuable addition into your resume by some employers. 

This means that as you move forward and with these courses, you might have to rely solely on your skill to land a job in some organizations. 


The prices vary and can cost you anywhere between $64.99 and $129.99. There is also a free course that you can enroll in. However, at the time of writing, the $64.99 course costs just $17.99 while the $129,99 course now costs just $11.99!

Bottom Line

When it comes to choosing the best GD&T training courses, what matters most is your intent. 

If you are truly looking to become an expert, we suggest going with any of the above-reviewed courses from beginner to expert-level.
