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.
Buxton is a spa town in Derbyshire, in the East Midlands region of England. It has the highest elevation – about 1,000 feet (300 m) above sea level – of any market town in England.[nb 1] Close to the county boundary with Cheshire to the west and Staffordshire to the south, Buxton is described as "the gateway to the Peak District National Park". A municipal borough until 1974, Buxton was then merged with other localities lying primarily to the north, including Glossop, to form the local government district and borough of High Peak within the county of Derbyshire. It is also near to Greater Manchester. The population of the town was 22,115 at the 2011 Census.
Buxton landmarks include Poole's Cavern, an extensive limestone cavern open to the public, and St Ann's Well, fed by the geothermal spring bottled and sold internationally by Buxton Mineral Water Company. Also in the town is the Buxton Opera House, which hosts several music and theatre festivals each year. The Devonshire Campus of the University of Derby is housed in one of the town's historic buildings.
Buxton is twinned with two towns: Oignies in France and Bad Nauheim in Germany.
