Course Description

GD&T Fundamentals teaches a simple framework that allows students to not only understand how Geometric Dimensioning and Tolerancing is used, but also why GD&T improves the manufacturing process. The course is focused on practical knowledge and uses real-world examples from our clients as instructional tools. GD&T Fundamentals doesn’t overwhelm students with every GD&T concept – the lessons are curated to teach students only the concepts and terminology necessary to do their jobs better and improve your manufacturing operation.

Course Objectives

By the time you complete this course, you’ll be able to:

  • Gain a mental framework and understanding that simplifies 95% of all GD&T  
  • Understand the main requirements and terminology of the ASME Y14.5 Standard in terms of plain English 
  • Learn all 14 major GD&T symbols and understand how to apply the symbols that are useful and to avoid the ones that aren’t  
  • Understand GD&T Feature Control Frames and how they affect manufacturing and inspection 
  • Know how Max Material Condition creates bonus tolerance while maintaining a functional part  
  • Understand datums and how they are applied on drawings for design, manufacturing, and inspection  
  • Understand how Geometric Dimensioning and Tolerancing is applied on physical parts and real-world drawings  
  • Know best practices and have a realistic approach for using GD&T in your job 

You’ll leave this course equipped to read, interpret, and understand GD&T on real engineering drawings—and empowered to work more confidently, communicate more clearly, and produce parts more efficiently.


Who it is for

The GD&T Fundamentals course takes our print reading course to the next step – by showing how Geometric Dimensioning and Tolerancing is used, interpreted, and applied across a part’s life cycle. This course is designed to be very approachable and geared towards everyone from entry-level to those with intermediate experience. To take this training, you should have some experience in a design, production or inspection environment working with engineering drawings. You should also be able to understand how parts are represented and viewed on a print. No prior GD&T knowledge is required, though! 


Requirements (Materials and Classes)

  • Print Reading & Tolerancing course is recommended before taking the GD&T Fundamentals, but not required
  • No prior GD&T experience needed
  • No additional materials to purchase – everything you’ll need is included (see below)

  • 6-month access from the date of purchase
    • Bundle with another course to receive 1-year access.
  • Direct instructor email support with access to pre-recorded video answers
  • Monthly - Live and pre-recorded webinars offering design, production, and inspection walk-throughs
  • Helpful charts, drawing examples, practice exercise worksheets, and other printable handouts
  • Quizzes and knowledge checks to gauge progress throughout the course
  • Certificate of course completion with 16 Professional Development Hours (PDH)

This course offers a great overview of all the key concepts of GD&T. I teach CNC machining at a technical school and found this course to be an excellent refresher on the topics I had encountered before in the workplace. The course taught me several new things about conditions and cases I had never experienced or considered, and cleared up some common misconceptions I had about GD&T practices. The material is delivered at a level that is accessible to all skill levels, from machinist apprentices to senior design engineers. The course is well formatted, contains excellent graphics and animations, and provides clear explanations for tricky topics. After just a few weeks, the GD&T Basics Fundamentals course can teach you everything you need to know to read and use GD&T in a manufacturing workplace.

Seriously though, I have yet to find a better way of understanding GD&T. This class has everything you need to learn the basics and even some more difficult applications of GD&T. The visual representations of everything make GD&T SO MUCH EASIER to understand.

Very step by step instructions, makes understanding GD&T quite accessible for the average person. Was able to understand the information in the format provided quite easily. Previously I had purchased a book on GD&T to get a better understanding of it, the book was not helpful as it would just state something without having explained the foundation of what it meant. Would highly recommend this class.

Good course

Gavin Amos

Great intro course. Retaking the final 3 times to pass it really drove home the concepts. Better than the course the Univ at Buffalo teaches for GD&T.
