Example of true position geometric control defined by basic dimensions and datum features. Geometric dimensioning and tolerancing (GD&T) is a system for defining and communicating engineering tolerances via a symbolic language on engineering drawings and computer-generated 3D models that describes a physical object's nominal geometry and the permissible variation thereof.
A material condition in GD&T. Means that a feature of size is at the limit of its size tolerance in the direction that leaves the most material on the part. Thus an internal feature of size (e.g., a hole) at its smallest diameter, or an external feature of size (e.g., a flange) at its biggest thickness. The GD&T symbol for MMC is a circled M.
Technical drawing with references and geometric specifications. A datum reference or just datum (plural: datums [Note 1]) is some geometrically 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 the object and (often) in measuring aspects of the actual geometry to assess how closely they ...
Coordinate dimensioning was the sole best option until the post-World War II era saw the development of geometric dimensioning and tolerancing (GD&T), which departs from the limitations of coordinate dimensioning (e.g., rectangular-only tolerance zones, tolerance stacking) to allow the most logical tolerancing of both geometry and dimensions ...

The datum feature is brought into contact with the datum simulator, which is to be of such quality as to be indistinguishable for the purpose from the theoretically perfect datum (gage maker tolerances)45.48.101.15 06:10, 24 February 2015 (UTC). In application, one can fix precision angle blocks on a CMM as datum simulators, probe them to ...
Schematic symbols for male and female connector pins. In electrical and mechanical trades and manufacturing, each half of a pair of mating connectors or fasteners is conventionally designated as male or female, [1] a distinction referred to as its gender. [2] The female connector is generally a receptacle that receives and holds the male connector.
