Geometric Dimensioning and Tolerancing provides thorough coverage of GDandT practices, as established by the ASME Y14.5 - 2009 standard. From understanding symbols on existing drawings to calculating the tolerances for proper size and location of features, topics are introduced in a methodicalmanner to establish an understanding of basic concepts before building to more advanced applications. Heavily illustrated, the use of the second color enhances learning by highlighting callouts and labels separately from the symbols and text of each drawing.
