  • 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

Why Students Love GD&T Fundamentals

GD&T Basics / Engineer Essentials LLC

Learning so much. I like your style. The presentations are thorough. The quizzes feel non-threatening and help cement the ideas.

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.

GD&T Basics / Engineer Essentials LLC

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.

GD&T Basics / Engineer Essentials LLC

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.
