Course description
If you know the fundamentals of GD&T but are looking to become the go-to expert in your office, shop or workplace then you have come to the right place. The GD&T Advanced Course takes your GD&T skillset to the next level by exploring the more specific and complex topics within the ASME Y14.5 Standard. Even though the material will be much more advanced, you can expect to find the same level of engaging, down-to-earth instruction that has helped thousands of students like you learn GD&T with our GD&T Fundamentals Course. Our lessons go beyond theory to show you how to apply these real world topics in actual applications and designs.
In this course, we delve into topics such as composite tolerances, fixed and floating tolerance calculations, hole pattern tolerancing, feature boundary calculations, and much more. You can expect to fill in any gaps in knowledge you may have about these more advanced topics while discovering a set of incredibly helpful tools that help you apply GD&T to your designs.
The GD&T Advanced Course is only available for existing GD&T Basics Course students and enrollment is limited. Only Students invited to this program will be able to enroll. Please contact us at info@gdandtbasics.com to for questions about availability and enrollment.
Tom Geiss
Founder - Pareto Learning / Lead Course Developer GD&T Basics
I have been in the field of Automotive Engineering with several companies including BMW Manufacturing and ZF Transmissions for over 8 years and truly love it. It is fast paced and an incredible field to be in. The ability to work on something for years and then actually get to see it out on the road is very rewarding.
My love of engineering led me to study the fundamentals of what makes a good design. Throughout my entire career, I have been studying Geometric Dimensioning and Tolerancing and how it could be better applied to the automotive and mechanical fields.
It is my belief that if you want to be a great designer, you need to be an expert at GD&T. However, for too long GD&T learning has been way too complicated. The barrier to entry for learning imperative design concepts is too high. In my early years, I continued to study in order to bridge the large gap between GD&T in theory and actually using GD&T in the real world. Everything came together for me when I figured out how GD&T concepts apply to real parts and their functional requirements. Years later, this prompted me to develop GD&T Basics, which explains the most important concepts and show learners how to apply what they learn in practical, real-world situations.

Well structured course modules
by Ajit Shetty
I really like the course structure as it helps to set milestones along the way and incrementally understand new concepts.
The final exam was not at all hard but if this is expected in the ASME exam then it sure is an easy one.
Only improvement - Case study assignments would help to further dive into concepts and better understand each module.

GD&T Water from a Fire Hose
by Deran Eaton
There's a running joke at MIT about the learning flow there being like drinking water from a fire hose -- the fire hose rigged into the drinking water fountain. That's what this Advanced GD&T course is like. Very substantial and thorough.
General Comments:
A) Section 8's real world applications can get a bit repetitive. I also discovered one error there (already reported). Some more variety might help loosen up the sense of repetition.
B) Since Section 8 dances around tolerance stackups in chained dimensions so often, the full course on tolerance stackups might be reasoned out algebraically. Remember, some of your audience doesn't fear reasoning out the math.

Advanced Course Comments
by David Vagi
This course covers much of the design side of the standards. I recommend it for any designer or mechanical engineer that desires to communicate to the manufacturing floor proper information to make mechanical components that will function as intended at the highest quality and lowest cost. I am a Master Machinist that has machined components for companies that properly spec their drawings and those that don't. GD&T specified drawings are a must in the current manufacturing world to be competitive.
