This is a free lite version of our digital guide to Geometric Dimensioning and Tolerancing (GD&T). It is written to the latest ASME Y14.5-2009 standard. The changes and improvements from previous standards are noted so the GeoTol Pro Digital Guide can be used to interpret earlier geometric tolerancing standards as well.
The guide contains the first 17 of the full 70 pages with the graphics in full color to make the concepts and tolerance zones easier to visualize. It has a table of contents for a quick search to necessary information.
The guide also contains a formula page for converting hole X and Y deviations to position tolerance zones.
The pocket guide is a necessary companion and a ideal reference to the major concepts and necessary formulas that are used every day by people working with GD&T.
