Geometric Dimensioning & Tolerancing (GD&T)
Based on ASME Y14.5-2009, this instructor-led introduction course simplifies GD&T learning using mostly visual material to explain basics of GD&T application, interpretation and verification as well as implications from design to manufacturing. Exercises are used throughout the course.
This instructor-led course simplifies GD&T learning, using mostly visual material, to explain basics of GD&T application, interpretation and verification as well as implications from design to manufacturing. Exercises are used throughout the course. Students learn faster and retain more information with visuals and 3D objects.

Rich was very knowledgeable and had a genuine interest in if the students understood the info he presented.
An amazing teacher! Every topic had its amount of time and he explained and answered all our questions. Everything he covered, I do in my job, everything went well!
Rich made course easy to learn with a very fair pace.
Materials were useful. Used Props – not just powerpoints.
Good teaching, well done!
