7 Top GD&T Training Courses Online

Here are the 7 best GD&T courses you can enroll in for greater knowledge of engineering flexibility.

1. GD&T Basics Online Training Course – Fundamentals

GD&T Basics Online Training Course – Fundamentals

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

Regarding geometric dimensioning and tolerancing training courses, GT&T Basics 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 is 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 a fundamentals course that won’t turn you into an expert. Instead, by the 8-10 lesson mark, you will be able to identify elements, make better decisions, and incorporate elements into the real world. 

The course allows 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 with a busy schedule), or go complete 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 subsequent, more advanced courses. 


The introductory course costs $399, with possible discounts that bring the price down to $299.

2. GD&T Basics Online Training Course – Drawing

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 regarding your query. 

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

The course has no prerequisites such as experience or engineering background. You start from the ground up and learn all you need about GD&T machining, product design, and more. 

We recommend this training program to all students 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 course – or you can go with the pre-made options. The course will cost you $199, but there is an ongoing promotion in which the course costs just $149.

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

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 to their resume. 

While the material is straightforward (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 covering everything – from GD&T fundamentals to every minute modifier you might 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 test your concepts of GD&T. 

However, the good news is you can 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, but with a discount, it costs $399.

4. SAE International – GD&T Fundamentals

SAE International – GD&T Fundamentals

  • Associated terms
  • Modifiers and adjustments (RFS, MMC, and more)

  • Identification of datum reference frames (RMB, MMB, and more)

You will also access the 2018 GD&T Pocket Guide to further your learning ventures.

5. Applied Geometrics Inc. – GD&T Training

Applied Geometrics Inc. – GD&T Training

The course consists of most machining concepts, datum features, and more. One of the best features of this training course is that you will get a certificate of completion after completing 80% of the course.

6. GeoTol – GD&T Fundamentals Program

GeoTol – GD&T Fundamentals Program

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

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


The course will set you back $299. Remember that this one isn’t the best for students.

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

Udemy Geometric Dimensioning and Tolerancing (GD&T) Courses

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

Udemy offers various GD&T training courses geared toward helping a non-specialist learn 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 standards are compliant and will help you on your road to becoming an expert product designer. 

However, there is one slight hitch that you need to keep in mind. Not all employers accept Udemy courses. 

As you move forward with these courses, you might have to rely on your skills to land a job in some organizations. 


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

Bottom Line

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

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