List of Courses, Seminars & Workshops

Level 1 GD&T Fundamentals Course

20 hours
Intense introduction to Geometric Dimensioning and Tolerancing. This course presents the components and the overall system of GD&T. We explain why GD&T is needed and the meaning of dimensioning and tolerancing and GD&T specifications. We introduce the concepts of Functional Dimensioning and Tolerancing and discuss Dimensioning and Tolerancing Philosophy. The material is presented from a multi-disciplinary point-of-view, paying careful attention to the legal implications of Engineering Specifications and their effect on all downstream processes, such as manufacturing, inspection, assembly, service, etc. Also useful for GD&T Certification Preparation. Course is coordinated with and prerequisite for other courses offered. Exercises included.

Level 2 GD&T Applications Course

20 hours
Expansion of GD&T Level I Course with extensive hands-on exercises and applications problems. Deeper coverage of complex geometries, Datum Reference Frames, Y14.5 vs. Y14.5.1 interpretations, Composite Tolerancing, Free-State vs. Restrained Parts, Tolerance Analysis issues, etc. Presentation and discussion of various applications and the effects of different approaches. Alternate strategies and optimal application are stressed in this course. Recommend prerequisite of prior completion of our GD&T Level I Course. Exercises included.

Level 3 Advanced GD&T Course

20 hours
Extended topics and Expansion of GD&T Level I & II Courses, problems and challenges in Dimensioning and Tolerancing, process-related issues, mathematical concepts, effects on Tolerance Stackups, etc. Presentation and discussion of various applications and optional strategies. Implications on downstream processes including manufacturing, inspection, assembly, service, etc. Recommend prerequisite of prior completion of our GD&T Level I & II Courses. Exercises may be included. (This course is customized to your products, drawings and processes.)

Fundamentals of GD&T – Learn and Understand Correct Application with GD&T Advisor for PTC® Creo® Training

20 hours
Presents a thorough explanation of the system of GD&T concepts, rules, legal issues, tools and techniques from design, inspection, manufacturing, and concurrent engineering points of view. This course covers all the fundamentals so you will understand the shortcomings of +/- Dimensioning and Tolerancing and how GD&T eliminates these deficiencies. Functional Dimensioning and Tolerancing, reasons to use GD&T, and practical applications are explained in detail. GD&T is addressed from the details to the system-level. While this is a technical course, topics are presented in the context of business, benefits and tradeoffs, risks and benefits for all departments and your supply chain. We offer the most comprehensive GD&T training on the market.
