Computer aided design or CAD involves the designer’s use of computer as an alternative to the more traditional types of drawing and modelling and it’s an indispensable tool for graphic and product designers, engineers, interior designers and architects. It helps the designers in making or preparing drawings, specifications, parts lists, and other design related elements using special graphics and computer programs that are calculation intensive. This technology is widely used for wide variety of fields such as architecture, shipbuilding, electronics, aerospace, prosthetics, naval and automotive engineering. Computer aided design is used widely to create computer animation for special effects in movies, advertising and technical manuals. CAD systems now include three-dimensional modelling and computer simulated operation of the model. The design of geometric models for use as object shapes is called computer aided geometric design (CAGD).
Computer aided design is used to design curves and figures in two – dimensional space or curves, surfaces, or solids in three – dimensional objects. Due to its enormous economic importance, computer aided design has been the major driving force behind research in computational geometry, computer graphics and discrete differential geometry. CAD is mainly used in the detailed engineering of 3D models or 2D models of physical components and throughout engineering process from conceptual design and layout of products to definition of manufacturing methods of components.
The people who work in this field are called: Designers, CAD Monkeys, Automotive Design Engineers, and Digital Innovation Engineers.
Lower product development costs
Its less expensive and is really affordable
Greatly shortened design cycle
Enables designers to layout and design or develop work on screen, print it out and save it for future editing, saving time on their drawings.
Improved and simplified user interfaces
User oriented modeling options which includes the ability to model or design a component with the help of large, even multi – CAD
Enhancements are done for the application software.
