Technical drawing, drafting or drawing, is the act and discipline of composing drawings that visually communicate how something functions or is constructed.
Technical drawing is essential for communicating ideas in industry and engineering. To make the drawings easier to understand, people use familiar symbols, perspectives, units of measurement, notation systems, visual styles, and page layout. Together, such conventions constitute a visual language and help to ensure that the drawing is unambiguous and relatively easy to understand. Many of the symbols and principles of technical drawing are codified in an international standard called ISO 128.
The need for precise communication in the preparation of a functional document distinguishes technical drawing from the expressive drawing of the visual arts. Artistic drawings are subjectively interpreted; their meanings are multiply determined. Technical drawings are understood to have one intended meaning.
A drafter, draftsperson, or draughtsman is a person who makes a drawing (technical or expressive). A professional drafter who makes technical drawings is sometimes called a drafting technician.
Grimsby, also Great Grimsby, is a large coastal English seaport and administrative centre in North East Lincolnshire, on the South Bank of the Humber Estuary, close to where it reaches the North Sea. It was the home port for the world's largest fishing fleet by the mid-20th century, but fishing fell sharply after the Cod Wars denied the United Kingdom access to Icelandic fishing grounds, and the European Union parcelled out fishing quotas in waters within a 200-nautical-mile (370 km) limit of the UK coast to other European countries, in line with its Common Fisheries Policy. Grimsby has since suffered post-industrial decline, although food production has spread since the 1990s. The Grimsby–Cleethorpes conurbation acts as a cultural and economic centre for much of north and east Lincolnshire. Grimsby people are called Grimbarians; the term codhead is also used jokingly, often for Grimsby football supporters. Great Grimsby Day is 22 January.
