GD&T Fundamentals - 3-day Course Syllabus

A typical onsite agenda for a Fundamentals of Geometric Dimensioning & Tolerancing course is shown below.

GD&T Fundamentals Typical 3-Day Onsite Course Outline

Note: Some training companies have spread this same content out into two, 2-day courses, which they typically call “Fundamentals” and “Advanced” GD&T, saving “more difficult to teach” topics (like composite vs. two single-segments) for the “Advanced” class. We’ve responded to the pressure of having increasingly greater content to teach by coming up with better ways to teach more content in a shorter period of time, allowing us to cover material in 3 days that many other companies require 4 days to cover.  Also, we are happy to customize the training to meet other time-lines or to include related content, including a version that emphasizes applications to fixtures and gaging described in ASME Y14.43-2011 Dimensioning & Tolerancing Principles for Gages and Fixtures.

Our instructors are available to travel to your facility to teach your people how to apply GD&T and/or tolerance stack analysis to your products using ASME Y14.5-2018, -2009, or -1994, and we can teach how GD&T applies to your gages using ASME Y14.43. 

Onsite training allows for more customization and application time and saves money, including eliminating travel costs for your participants. For a free quote for onsite Reading Engineering Drawings (typically 1 day), GD&T Fundamentals (typically 3-days as outlined above), or Tolerance Stack Analysis Using GD&T (typically 2-days), call: (586) 693-0219 or email: contact@gd-t.com

We'll need to know an approximate number of trainees, the location, and desired dates, and we'll check the travel costs and send you a PDF quote for the training that includes a detailed outline and explains everything that's included.

We've taught in the US, Canada, Mexico, Europe, and China, and we can arrange for a Spanish-speaking instructor. We can also offering courses of different lengths for different audiences and budgets.
