There are no prerequisites for using these materials. If you have had manual or CAD graphics, or machine shop background in high school, college, or in an industrial application, you may find some of the introductory materials repetitive and less challenging. However, because all of the materials parallel the ASME Y14.5M - 1994 standard, there is a strong possibility that some portion of the information will be new and challenging to you.

Engineering Graphics Principles with Geometric Dimensioning and Tolerancing is comprised of both a print book and digital content. A major portion of the instructional material is included on the digital download. The digital materials include exercises and self-evaluation materials.

More than anything else, these materials deal with modeling and defining part geometry on mechanical components and assemblies. Everything in the materials point to the importance of appropriate specification and control of part geometry, including: dimensioning, tolerancing, and verification of geometric characteristics and relationships.

The book begins with an abbreviated overview of the historical significance of graphics as a means of conveying and documenting design iterations and modeled configurations. However, it stops short of philosophizing on the design process and cycles of design.

Four specific modules have been designed to assist you in the introduction and/or review of basic concepts related to elements of view selection, orientation, projection, and standards for defining geometry. These units focus on orthographic projection, auxiliary views, sectioning, and coordinate dimensioning and tolerancing.
