Patrick J. McCuistion, Ph.D., GDTPS, was an Associate Professor in the Engineering Technology and Management Department at Ohio University for 25 years. He taught Engineering Graphics, Geometric Dimensioning and Tolerancing, Dimensional Analysis, Quality Management Systems, Microsoft Office Suite, and Technical Writing. Prior to that, he taught three years at Texas A&M University and one year at Pittsburg State University. He worked eight years in various engineering design, drafting, and design and drafting checking positions. He has provided instruction in geometric dimensioning, dimensional analysis, gage and fixture design, and dimensional metrology to industry, military, and educational institutions since 1986. He is certified as an ASME Geometric Dimensioning Tolerancing Professional – Senior grade and as an ADDA Mechanical Drafter.
Dr. McCuistion has authored one book on geometric dimensioning, teaching courses on the following subjects: Drawing Interpretation, Basic Geometric Dimensioning and Advanced Geometric Dimensioning, and authored two, ASME self-study courses covering Drawing Formats, Line Conventions and Lettering, Orthographic and Pictorial Views, Dimensioning and Tolerancing, and Drawing Revisions.
Dr. McCuistion is active in the following ASME/ANSI codes and standards committees: Y14 Main, Y14.2 Line Conventions and Lettering, Y14.3 Orthographic and Pictorial Views, Y14.5 Dimensioning and Tolerancing, Y14.5.1 Mathematical Definition of Dimensioning and Tolerancing Principles, Y14.5.2 Certification of Geometric Dimensioning and Tolerancing Professionals, Y14.8 Castings, Forgings, and Molded Parts, Y14.35 Revision of Engineering Drawings and Associated Documents, Y14.36 Surface Texture Symbols, Y14.43 Dimensioning and Tolerancing Principles for Gages and Fixtures, Y14.45 Measurement Data Reporting, and Y14/B89 Joint Advisory Committee (JAC1) on the Specification of Notation to Support Requirements for Size and Geometric Tolerances.
As Chair of the national SkillsUSA Technical Drafting competition, Dr. McCuistion creates the yearly design and drafting problem with solutions and a written test and coordinates all competition details. The problem to be solved includes drawing and assembling 3D computer models of a product and creating dimensioned 2D views of those models based on national drawing standards.
Edward McCarthy has 48 years of industry experience in product definition and technical data package. In 2017, he started providing services to industry in consulting, monitoring, and formal training for product definition and design intent.
Ed started his career within the U.S. Air Force Communication Command within an Engineering Squadron in the development of military engineering programs. Ed has a broad range of industries experiences in product design for the Dept. of Defense (DoD) projects, aerospace, expandable space-stations, electron beam accelerators, product handling equipment, high speed winders, semiconductor robotics, laser imaging systems, linear accelerator systems, medical, weapons and missile systems.
Ed specialized as an internal subject matter expert and taught formal classes within the above industries dealing with dimensioning and tolerancing for product definition, tolerance analysis, measurement reporting and inspection. Ed has trained thousands of professionals in Print Reading, Geometric Dimensioning and Tolerancing (GD&T), Geometric Tolerancing Applications, and Tolerance Analysis. He has developed specialized training material in dimensioning and tolerancing within the different companies at which he was employed at.
Ed is Senior Level GDTP certified to ASME Y14.5.2 and is an active member of the following committees related to GD&T:

John I. Miles is a Senior Instructor, coach, and mentor. He has over 35 years’ experience as a Senior Tool Designer and Dimensional Management SME, which includes 12 years as a quality tool designer and 16 years as a GD&T (Geometric Dimensioning and Tolerancing) specialist and trainer. John retired from Lockheed Martin Aeronautics Co. in Fort Worth, TX in 2014, after 28+ years. He was the Lockheed Martin Corporate subject matter expert for dimensional management – GD&T and was the chair of the Corporate Community of Practice (CoP). John has taught over 5,400 individuals in various levels of GD&T throughout the corporation and with their many machine parts suppliers both domestic and international. John was instrumental in the transition from fully dimensioned 2D drawing practices to a model-based definition (MBD – reduced dimensioned drawing) concept for the F-35 program as well as others throughout the corporation.
John has a down to earth presentation style of instruction and adds humor and fun to the learning experience which produces high ratings from those attending his GD&T and Engineering Drawing Standards Seminars. John stresses that no question is too small and that even the simplest question answered incorrectly can be costly to their company.
John also brings extensive experience as a GD&T mentor, working on-site, side-by-side, helping our customers apply GD&T principles to day-to-day real-world applications. His expertise and skills were developed while employed at: Lockheed Martin Aeronautics Co in Fort Worth, TX, Lockheed Martin Missiles & Fire Control in Orlando, FL, and at Texas Instruments in Dallas, TX.
