GD&T Symbols in the Tolerances & Datum fonts meet ASME/ANSI Y14.5M-1994 and QS-9000 specifications.

In 1992, Page Studio Graphics created the original set of GD&T (Geometric Dimensioning and Tolerancing) symbol fonts in PostScript and TrueType, for engineering documentation prepared on either the Macintosh or PC/Win. Over the years we also designed several custom versions, for engineering firms as well as for engineering software developers who offer licensing for these fonts.

The Page Studio Graphics font foundry was established in 1986 with the primary purpose of producing high quality special purpose symbol fonts.
