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.
Corby is a town and borough in the county of Northamptonshire, England.
It is located 23 miles (37 km) north-east of the county town, Northampton. At the 2011 Census the town had a population of 54,927 and the borough had a population of 61,255. Figures released in March 2010 revealed that Corby has the fastest growing population in both Northamptonshire and the whole of England. The borough of Corby borders onto the borough of Kettering, the district of East Northamptonshire, the district of Harborough and the unitary authority county of Rutland. The town was at one time known locally as "Little Scotland" due to the large number of Scottish workers who came to Corby for its steelworks. Recently, Corby has undergone a large regeneration process with the opening of Corby railway station and Corby International Pool in 2009 and the Corby Cube building opening in 2010. This is home to Corby Borough Council offices and also houses a 450-seat theatre, a public library and other community amenities.
