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 ...

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 references (if required by the GD&T Symbol) Combined, the feature control frame provides all the information you need to measure the geometric tolerance of the features of the part and determine if the part …

Datums are used in GD&T drawings to create a reference system for inspecting a manufactured part. This reference system is called a Datum Reference Frame (DRF).
