- geometric dimensioning
The GD&T Hierarchy textbook is intended to aid in the instruction of Geometric Dimensioning and Tolerancing (GD&T) in accordance with the ASME Y14.5-2009 standard as well as the ASME Y14.5M-1994. Where a concept is new to the 2009 revision of the Standard it has a shaded background. Coverage also includes selected topics from ASME Y14.41.
This full color text is in landscape format which made it possible to include more complex drawings than are usually found in a GD&T text. There are over 200 pages with many illustrations of drawings and solid models of actual parts drawn from industry. In addition to containing the rules, terms and definitions of GD&T, this text makes exclusive use of the GD&T Hierarchy to explain the relationship between tolerances and to guide the reader to the most appropriate applications.
