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.
Suffolk (/ˈsʌfək/) is an East Anglian county of historic origin in England. It has borders with Norfolk to the north, Cambridgeshire to the west and Essex to the south. The North Sea lies to the east. The county town is Ipswich; other important towns include Lowestoft, Bury St Edmunds, Newmarket, and Felixstowe, one of the largest container ports in Europe.
The county is low-lying but it has quite a few hills (especially more to the west), and has largely arable land with the wetlands of the Broads in the north. The Suffolk Coast and Heaths are an Area of Outstanding Natural Beauty.
