Advanced Concepts of GD&T 1994 3-day

This course teaches the advanced concepts of GD&T as prescribed in the ASME Y14.5M-1994 Standard and can be conducted with flexible scheduling including 5 mornings or 5 afternoons.   

Utilizing the expertise of world-renowned GD&T expert Alex Krulikowski, this course offers an in-depth explanation of advanced GD&T topics like composite tolerancing, tolerance analysis, datum selection, non-rigid part dimensioning, and many more key dimensioning topics, including the system approach for part dimensioning. Newly acquired learning is reinforced throughout the class with more than 250 practice problems.

Each attendee receives a robust collection of learning resources including:
  • Advanced Concepts of GD&T (ASME Y14.5M-1994) textbook
  • GD&T Ultimate Pocket Guide 
  • Fundamentals of GD&T Exercise Workbook
  • 90-day access to Fundamentals of GD&T 1994 web training course
Thousands of students have learned GD&T through Alex Krulikowski"s textbooks, self-study courses, computer based training, and online learning center. Students who attend this course walk away with more than knowledge—they gain on-the-job skills because the learning materials are performance-based.
