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.
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.
In 2004, the Reduced-Size MultiMediaCard (RS-MMC) was introduced as a smaller form factor of the MMC, with about half the size: 24 mm × 18 mm × 1.4 mm. The RS-MMC uses a simple mechanical adapter to elongate the card so it can be used in any MMC (or SD) slot. RS-MMCs are currently available in sizes up to and including 2 GB.

Engineers analyze tolerances for the purpose of evaluating geometric dimensioning and tolerancing (GD&T). Methods include 2D tolerance stacks, 3D Monte Carlo simulations , and datum conversions. Tolerance stackups or tolerance stacks are used to describe the problem-solving process in mechanical engineering of calculating the effects of the ...
It was revised by MIL-STD-8A in 1953, which introduced the concept of modern GD&T "Rule 1". [5] [6] Further revisions have continued to add new concepts and address new technology like computer aided design and model-based definition. A list of revisions follows: [6] ASME Y14.5-2018, "Dimensioning and Tolerancing" Current Standard

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 ...
