The Advanced Concepts of GD&T 2009 coursebook is based on ASME Y14.5-2009. Topics covered are considered more complex and are often applied by specific industries, on specific types of components, or for specific situation. Examples in this book relate more closely with certain products and will be more complicated in nature, such as nonrigid parts, patterns of features as datum features, and more complex composite position and profile tolerancing. Many of the examples used include explanations of tolerancing concepts that may be problematic in the workplace. This coursebook requires the reader to already possess an understanding of the basics of GD&T and is intended for designers, product engineers, manufacturing and assembly engineers, CMM operators, and quality engineers
