However, symbols can be meaningful only if they are created according to the relevant standards or conventions. This document describes and illustrates common dimensioning, GD&T, architectural, piping, and electrical symbols.  \nStandard Dimensioning Symbols  \nThe size of dimensioning symbols varies with text size, but it should be consistent with the height of the text. In the following illustration, h = text height.  \n\n| Standard Dimensioning Symbols |\n| --- |\n| \u003Cbr>\u003Cbr>Diameter Radius \u003Cbr>\u003Cbr>Spherical Spherical Controlled Places\u003Cbr>\u003Cbr>\u003Cbr>|\n\nCopyright Goodheart-Willcox Co. , Inc.
