CAD

​Computer-aided design (CAD) is the use of computers (or workstations) to aid in the creation, modification, analysis, or optimization of a design.[1] 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.[2] 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.[3]

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.[4]

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.[5][6]: 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.[7]

The design of geometric models for object shapes, in particular, is occasionally called computer-aided geometric design (CAGD).[8]

​Bournemouth (/ˈbɔːrnməθ/ (audio speaker iconlisten)) is a coastal resort town on the south coast of England. At the 2011 census, the town had a population of 183,491. With Poole to the west and Christchurch in the east, Bournemouth is part of the South East Dorset conurbation, which has a population of 465,000.

Before it was founded in 1810 by Lewis Tregonwell, the area was a deserted heathland occasionally visited by fishermen and smugglers. Initially marketed as a health resort, the town received a boost when it appeared in Augustus Granville's 1841 book, The Spas of England. [1]Bournemouth's growth accelerated with the arrival of the railway, and it became a town in 1870. Part of the historic county of Hampshire, Bournemouth joined Dorset for administrative purposes following the reorganisation of local government in 1974. Through local government changes in 1997, the town began to be administered by a unitary authority independent of Dorset County Council, although it remains part of that ceremonial county. Since April 2019 the unitary authority has been merged with that of Poole, as well as the non-metropolitan district of Christchurch to create the Bournemouth, Christchurch and Poole unitary authority.

The town centre has notable Victorian architecture and the 202-foot (62 m) spire of St Peter's Church, one of three Grade I listed churches in the borough, is a local landmark. Bournemouth's location has made it a popular destination for tourists, attracting over five million visitors annually with its beaches and popular nightlife. The town is also a regional centre of business, home of the Bournemouth International Centre or BIC, and a financial sector that is worth more than £1 billion in gross value added.
