Applications of GD&T 2-Day

This course teaches the thought processes involved in assigning GD&T to components and will change the way many engineers think about part tolerancing.

The course focuses on what constitutes good and poor drawing practices, common dimensioning methods used in industry, using GD&T to communicate system functions on component dimensions, and the logic of how to apply GD&T to components.

Newly acquired learning is reinforced when students perform a design function analysis on a part assembly provided by your company, then specify GD&T on assembly components during the workshop. (This is optional in case of concerns over drawings and privacy.)

Each attendee receives a robust collection of learning resources including:

  • A copy of Applications of GD&T Workshop Exercise Workbook
  • Course notes
  • Drawing handouts
Thousands of students have learned GD&T through SAE textbooks, self-study courses, computer-based training, and online learning center. Students who attend courses like this one walk away with more than knowledge. They gain on-the-job skills because the learning materials are performance-based.

What Will You Learn

By attending this class, you will learn how to do a design functional analysis on an assembly and use this information to assign dimensions and tolerances. They will also learn how to select datum features and how to fully define component surfaces using GD&T. Establishing tolerance values is not covered. Small groups (8-12) are most effective in this workshop. The students will work in teams and actually create GD&T tolerance mark-ups of their company parts in the workshop. By attending this class, you will be able to:
  • Describe the importance of technically correct drawings
  • List three major areas that affect the creation and interpretation of technically correct drawings
  • Explain the common approaches to part tolerancing
  • Indentify and specify datum features based on the fit and functional requirements of the part
  • Use GD&T to communicate functional requirements of a component
  • Describe how to specify nonfunctional dimensions
  • Explain the five-step approach to functionally dimensioning a component
  • Apply the five-step method to functionally dimensioning a component to your company product
