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.
Wales (Welsh: Cymru [ˈkəm.rɨ] (audio speaker iconlisten)) is a country that is part of the United Kingdom. It is bordered by England to the east, the Irish Sea to the north and west, and the Bristol Channel to the south. It had a population in 2011 of 3,063,456 and has a total area of 20,779 km2 (8,023 sq mi). Wales has over 1,680 miles (2,700 km) of coastline and is largely mountainous with its higher peaks in the north and central areas, including Snowdon (Yr Wyddfa), its highest summit. The country lies within the north temperate zone and has a changeable, maritime climate.
Welsh national identity emerged among the Britons after the Roman withdrawal from Britain in the 5th century, and Wales is regarded as one of the modern Celtic nations. Llywelyn ap Gruffudd's death in 1282 marked the completion of Edward I of England's conquest of Wales, though Owain Glyndŵr briefly restored independence to Wales in the early 15th century. The whole of Wales was annexed by England and incorporated within the English legal system under the Laws in Wales Acts 1535 and 1542. Distinctive Welsh politics developed in the 19th century. Welsh Liberalism, exemplified in the early 20th century by David Lloyd George, was displaced by the growth of socialism and the Labour Party. Welsh national feeling grew over the century; a nationalist party, Plaid Cymru was formed in 1925, and the Welsh Language Society in 1962. Established under the Government of Wales Act 1998, the Senedd (the Welsh Parliament, formerly known as the National Assembly for Wales) is responsible for a range of devolved policy matters.
At the dawn of the Industrial Revolution, development of the mining and metallurgical industries transformed the country from an agricultural society into an industrial nation; the South Wales Coalfield's exploitation caused a rapid expansion of Wales' population. Two-thirds of the population live in South Wales, including the capital Cardiff along with Swansea, Newport and the nearby valleys. The eastern region of North Wales has about a sixth of the overall population with Wrexham being the largest northern town. The remaining parts of Wales are sparsely populated. Now that the country's traditional extractive and heavy industries have gone or are in decline, the economy is based on the public sector, light and service industries, and tourism. In livestock farming, including dairy farming, Wales is a net exporter, contributing towards national agricultural self-sufficiency.
Wales closely shares its political and social history with the rest of Great Britain, and a majority of the population in most areas speaks English as a first language, but the country has retained a distinct cultural identity. Both Welsh and English are official languages; over 560,000 Welsh-speakers live in Wales, and the language is spoken by a majority of the population in parts of the north and west. From the late 19th century onwards, Wales acquired its popular image as the "land of song", in part due to the eisteddfod tradition. At many international sporting events, such as the FIFA World Cup, Rugby World Cup and the Commonwealth Games, Wales has its own national team. At the Olympic Games, Welsh athletes compete for the UK as part of a Great Britain team. Rugby union is seen as a symbol of Welsh identity and an expression of national consciousness.
