The GD&T Hierarchy Pocket Guide Y14.5-2009
- ASME Y14.5-2009
Here is the Geometric Dimensioning and Tolerancing pocket guide you have been waiting for. All illustrations are in full color. By using solid models of real parts, 3-D illustrations of datums and geometric tolerance zones and extensive use of color it was possible to create a handy guide that clearly explains the meaning of GD&T. This is the biggest little pocket guide there is. There are over 130 pages of GD&T that will fit in your pocket. Everything is in accordance with the ASME Y14.5 standard (both 1994 and 2009 revisions). Where a concept is referencing the 2009 revision of the standard, the text is shaded in green.
