Everything about Datum reference
Point of reference against which some others are calculated
A datum reference or just datum is some geometrically important part of an object, such as a point, line, plane, hole, set of holes, or pair of surfaces. It serves as a reference in defining the geometry of the object and (often) in measuring aspects of the actual geometry to assess how closely they match with the nominal value, which may be an ideal, standard, average, or desired value.
