WebUnderstanding Datums. A clear reference is necessary for specifying a target’s orientation tolerance, location tolerance, and profile tolerance —that clear reference is the datum. A datum is a theoretical, ideal feature such as plane, line, or point, which does not actually exist: this makes it difficult to understand. WebDatum 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 face side, B is the first datum edge ... did fox news fire eric bolling
