WebClassification and Symbols of Geometric Tolerance Characteristics. The following is a list of symbols used for geometric tolerancing. “Single feature” under “Feature level” means features that are independent of datums (i.e. that do not require reference datum indication). A datum is a theoretical, ideal feature established to determine ... Datum reference frames are used as part of the feature control frame to show where the measurement is taken from. A typical datum reference frame is made up of three planes. For example, the three planes could be one "face side" and two "datum edges". These three planes are marked A, B and C, where A is the … See more A datum reference or just datum (plural: datums ) is some important part of an object—such as a point, line, plane, hole, set of holes, or pair of surfaces—that serves as a reference in defining the geometry of … See more In carpentry, an alternative, more common name is "face side" and "face edge". The artisan nominates two straight edges on a workpiece as the "datum edges", and they are marked accordingly. One convention is to mark the first datum edge with a single slanted line (/) and … See more An engineering datum used in geometric dimensioning and tolerancing is a feature on an object used to create a reference system for See more • Datum (geodesy) • Exact constraint • Reference frame • Surface plate See more
