In ISO 8666 for small boats, there is a definition of LOH, or length of hull. [9] This may be shorter than a vessel's LOA, because it excludes other parts attached to ...

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.
Geometrical Product Specification and Verification (GPS&V) [1] is a set of ISO standards developed by ISO Technical Committee 213. [2] The aim of those standards is to develop a common language to specify macro geometry (size, form, orientation, location) and micro-geometry (surface texture) of products or parts of products so that the language can be used consistently worldwide.

A standard format defined by ISO 10303 for MBD data generation, storage, and exchange. STA: solution treated and aged: STI: screw thread insert STL: steel: STK: stock: A nominal dimension for the stock material, such as bar stock: SW: Schlüsselweite: Translates as Key or Wrench Width. Width across flats, often found on drawings of German origin.
Beam diameter is usually used to characterize electromagnetic beams in the optical regime, and occasionally in the microwave regime, that is, cases in which the aperture from which the beam emerges is very large with respect to the wavelength. Beam diameter usually refers to a beam of circular cross section, but not necessarily so.
H7/h6 is a very common standard tolerance which gives a tight fit. The tolerances work in such a way that for a hole H7 means that the hole should be made slightly larger than the base dimension (in this case for an ISO fit 10+0.015−0, meaning that it may be up to 0.015 mm larger than the base dimension, and 0 mm smaller).
