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.
Tamworth (/ˈtæmwərθ/) is a large market town and borough in Staffordshire, England, 14 miles (23 km) north-east of Birmingham and on the West Coast Main Line. The town adjoins Warwickshire to the south and east, Lichfield to the north and west and local junctions of the M6 Toll motorway. It takes its name from the River Tame, which flows through it. Its resident population (mid-2019 est.) was 76,696.
Tamworth was historically divided between Warwickshire and Staffordshire until 1889, when the town was placed entirely in Staffordshire.
Tamworth hosts a simple but elevated 12th century castle, a well-preserved medieval church (the Church of St Editha) and a Moat House. Tamworth was the capital of the Anglo-Saxon Kingdom of Mercia during the Heptarchy of seven kingdoms and throughout its later, greater, form.
The town's industries include logistics, engineering, clothing, brick, tile and paper manufacture. Until 2001 one of its factories was Reliant, which produced the Reliant Robin three-wheeler car and the Reliant Scimitar sports car.
The Snowdome, a prototype real-snow indoor ski slope is in Tamworth and 1.7 miles (2.7 km) south is Drayton Manor Theme Park and one of the many marinas serving the Coventry Canal and Birmingham and Fazeley Canal which combine south of the town.
