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).
East Anglia in the East of England comprises the four counties of Norfolk, Suffolk, Cambridgeshire and Essex and is close to London. It is well-connected with Europe and the rest of the world through London Stansted Airport, the International Gateway to the East of England. There is also Norwich International Airport and London Southend Airport. The region has an excellent rail service with Greater Anglia, including the Stansted Express.
A recent report shows that East Anglia is home to three out of five of the fastest-growing city economies in the UK. Cambridge topped the list, with Ipswich second and Norwich fifth nationally according to The UK Powerhouse study.
The report reveals that Ipswich had the second-highest rate recorded of GVA growth rate (a measure of the value of goods and services produced) in the UK in the first three months of the year (2.5%), while Norwich enjoyed a growth rate of 2.4%.
Looking forward, the report also predicts the three locations will maintain their top 10 positions by the final quarter of 2028.
