Computer Aided Design
Computer-aided design (CAD) is the use of computers (or workstations) to aid in the creation, modification, analysis, or optimization of a design. This software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to create a database for manufacturing. Designs made through CAD software are helpful in protecting products and inventions when used in patent applications. CAD output is often in the form of electronic files for print, machining, or other manufacturing operations. The terms computer-aided drafting (CAD) and computer aided design and drafting (CADD) is also used.
Its use in designing electronic systems is known as electronic design automation (EDA). In mechanical design it is known as mechanical design automation (MDA), which includes the process of creating a technical drawing with the use of computer software.
CAD software for mechanical design uses either vector-based graphics to depict the objects of traditional drafting, or may also produce raster graphics showing the overall appearance of designed objects. However, it involves more than just shapes. As in the manual drafting of technical and engineering drawings, the output of CAD must convey information, such as materials, processes, dimensions, and tolerances, according to application-specific conventions.
CAD may be used to design curves and figures in two-dimensional (2D) space; or curves, surfaces, and solids in three-dimensional (3D) space.: 71, 106
CAD is an important industrial art extensively used in many applications, including automotive, shipbuilding, and aerospace industries, industrial and architectural design, prosthetics, and many more. CAD is also widely used to produce computer animation for special effects in movies, advertising and technical manuals, often called DCC digital content creation. The modern ubiquity and power of computers means that even perfume bottles and shampoo dispensers are designed using techniques unheard of by engineers of the 1960s. Because of its enormous economic importance, CAD has been a major driving force for research in computational geometry, computer graphics (both hardware and software), and discrete differential geometry.
The design of geometric models for object shapes, in particular, is occasionally called computer-aided geometric design (CAGD).
Coventry (/ˈkɒvəntri/ (About this soundlisten) KOV-ən-tree or /ˈkʌv-/ KUV-) is a city, administrative centre and metropolitan borough in England and the United Kingdom. It is built on the River Sherbourne, which remains largely hidden by infrastructure, although it can be seen by the canal. Coventry has been a large settlement for centuries, although it was not founded and given its city status until the Middle Ages; since then it has been one of the most important and largest cities of the country. The conurbation consists of the Coventry and Bedworth Urban Area, being the 20th largest in the country; the city is governed by Coventry City Council.
Historically part of Warwickshire, at the 2011 census Coventry had a population of 316,915, making it the 9th largest city in England and the 11th largest in the United Kingdom. It is the second largest city in the West Midlands region, after Birmingham, and is separated from the West Midlands conurbation by the Meriden Gap.
Coventry is 19 miles (31 km) east-southeast of Birmingham, 25 miles (40 km) southwest of Leicester, 11 miles (18 km) north of Warwick and 94 miles (151 km) northwest of London. Coventry is also the most central city in England, being only 12 miles (18 km) south-southwest of the country's geographical centre in Leicestershire; it is located in the West Midlands.
The current Coventry Cathedral was built after most of the 14th century cathedral church of Saint Michael was destroyed by the Luftwaffe in the Coventry Blitz of 14 November 1940. Coventry motor companies have contributed significantly to the British motor industry. The city has three universities, Coventry University in the city centre, the University of Warwick on the southern outskirts and the smaller private Arden University, with its headquarters close to Coventry Airport.
On 7 December 2017, the city won the title of UK City of Culture 2021, after beating Paisley, Stoke-on-Trent, Swansea and Sunderland to the title. It will be the third title holder of the quadrennial award which began in 2013. In July 2020 it was announced that the City of Culture festivities would not commence until May 2021 and conclude in May 2022 due to preparational and infrastructural delays caused by the COVID-19 pandemic. Following this Coventry City of Culture Trust released a manifesto film, celebrating the city of Coventry and announcing the brand for Coventry UK City of Culture 2021, 'Coventry Moves'.
