Advanced Concepts of GD&T (2009) 2-day ET3016


This course teaches the advanced concepts of GD&T as prescribed in the ASME Y14.5-2009 Standard and offers an in-depth explanation of advanced GD&T topics not covered in our Fundamentals training.  Complex topics include expanded use of composite position and profile tolerances, customized datum reference frames, the translation modifier, and applying GD&T to non-rigid parts. Learning is enforced interactive engagement between the instructor and the students, followed with numerous exercises at the end of each chapter.

Each attendee receives a robust collection of learning resources including:
  • Advanced Concepts of GD&T coursebook (ASME Y14.5-2009)
  • A GD&T Ultimate Pocket Guide (2009)
  • 90-day access to Fundamentals of GD&T 2009 web training course 

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 and taught by experienced instructors who have applied GD&T in industry.
