GD&T Comprehensive Fundamentals (Virtual Classroom)

 

This course is a 3-day immersion into the rules, symbols, and other concepts of the American Standard for Geometric Dimensioning & Tolerancing: ASME Y14.5-2018. The course also covers important differences between older versions of the standard and the current ISO GD&T Standards. Key fundamental rules, all control symbols, datums and datum schemes, basic dimensions, virtual conditions, modifiers, and the infamous Rule #1 are all covered in detail.

This course includes a variety of examples and short exercises that will help you progressively learn more about this unique design language. Participants will work through various exercises and have the opportunity to review engineering drawings during the course.

​

By participating in this course, you will learn how to successfully:

• Describe the tolerance zones defined by each symbol, and whether a control symbol can be applied to a surface only, a feature of size only, or either one.

• Determine when to use Rule #1 to control form and when other controls are appropriate.

• Recognize correct syntax for feature control frames.

• Identify and reference datums correctly.

• Assess various datums and datum schemes against product functionality and manufacturing and inspection performance.

• Relate common gauging and inspection methods to geometric tolerance zones defined by feature control frames.

• Correctly apply and interpret the Maximum Material Condition (MMC), Least Material Condition (LMC), and all other modifiers.

• Correctly calculate virtual condition, resultant condition, and maximum material boundaries.​

• Correctly calculate bonus and datum shift.

 

Who should attend?

You should have some familiarity with engineering drawings, but you do not need any previous GD&T experience. Many participants looking for advanced classes discover that their GD&T skills are challenged by the fast pace and in-depth coverage of our fundamentals course. Come prepared to work hard and learn a lot, even if it's not your first time through a GD&T class.
