CAD the shortening for Computer-aided design
By: amtanda12Computer-aided design (CAD) is deployed for designing real and virtual objects. CAD often involves more than just shapes. The output of CAD commonly must also contain symbols, for example processes, dimensions and tolerances according to conventions of an application.
CAD can be used to design curves and figures in two-dimensional (2D) space, or curves, surfaces and solids in 3-dimensional (3D) space.
Computer-aided design is extensively used in automotive, ship-building and aerospace industries, industrial and architectural design, prosthetics etc. CAD is also extensively used to make computer animation for special effects in films, commercials and technical instructions. CAD is used for designing tools and machinery as well as for drawing and designing all kinds of architectural structures, from houses to the largest commercial and industrial buildings, such as hospitals and factories. CAD is primarily used for detailed engineering of 3D models or 2D drawings of physical components, but it is also used throughout the engineering process. People who work in this field are called designers, CAD Monkeys, Automotive design Engineers and Digital Innovation Engineers. Computer-aided design is also a regular work activity for the traditional engineering professions.
CAD has become an exceptionally important technology among computer-aided technologies, since it saves both time and money.
In the late 1980s when the Computer-Aided Design programs became widely available, there began massive redundancies in drawing departments of small and mid-size companies. A CAD operator could supersede 3-5 drafters deploying traditional techniques. Moreover, a number of engineers began their own drawing projects, therefore the need for traditional drawing departments vanished. Consequently, a lot of people were laid off.
Being rather expensive, the advances were chiefly bought by large companies. Therefore, small companies were unable to compete against giants that widely deployed CAD. Nowadays, prices are lower. Even high-end software packages need less expensive platforms and some even support multiple platforms.
In addition, there have been introduced diverse software packages to convert CAD files to other formats.
