Length: 43 days    CEUs: 2.30    PDHs: 23.00

This course covers the majority of information required to understand basic mechanical two-dimensional engineering drawings.  Topics covered are:
 - Basic drawing elements (formats, title block, parts list, revision block, etc.)
 - Part views (multiview, auxiliary, and isometric)
 - Section views
 - General dimensions
 - Tolerances
 - Finish and welding symbols.

The course consists of nine modules, each with a quiz; most also include drawing assignments and supplementary information.  As reference material, a drawing packet is included that shows five detail drawings and an assembly drawing for the parts of a Trolley Wheel. The package includes flat and round parts and a casting.  Possession of the ASME Y14.5 Dimensioning and Tolerancing Standard is recommended.

This is an online, instructor-supported course, allowing you to work at your own pace and convenience.

You Will Learn To
 - Describe the fundamentals of drawing interpretation
 - Identify drawing elements, including part views and sections
 - Describe general dimensions and tolerances
 - Explain how to present surface texture, fasteners and welding

Patrick J. McCuistion, Ph.D., GDTPS, created all the figures for the Y14.43 standard. He was an Associate Professor in the Engineering Technology and Management Department at Ohio University for 25 years. He taught 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. Dr. McCuistion worked for eight years in various engineering design, drafting, and design and drafting checking positions. He has provided instruction in geometric dimensioning, dimensional analysis, and dimensional metrology to industry, military, and educational institutions since 1986. He has authored one book on geometric dimensioning, three ASME Instructor-supported online courses on Drawing Interpretation, Basic Geometric Dimensioning and Advanced Geometric Dimensioning, and two ASME self-study internet 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, Y14.5.2 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, and Y14/B89 Joint Committee on the Specification of Notation to Support Requirements for Size and Geometric Tolerances.
