Computer Aided Design (CAD) is a form of software automation tools for various computer-aided design engineers, architects and other professionals in the design activity for assistance. It is considered both the software and hardware for special purposes. In managing the lifecycle of the product, the use of geometrical instruments plays an important role. The DAC is available in different sizes, ranging from 2D vector systems Drafting 3D parametric surface and solid design modelers.
CAD drawings can prepare accurate and fast. Almost anything can be built and constructed as a design model developed in the CAD system. The flexibility to change designs is very easy to achieve with minimal effort. It is also known as computer aided design and drafting (CADD). It is sometimes translated by computer aided design or computer. The tool offers a better and faster to develop designs with greater creativity.
CAD is used in large regions such as the applications of computer graphics, computer-aided manufacturing, solid modeling, problem solving, the purpose and architecture of VLSI design process. Other areas that use CAD architecture and construction, buildings (AEC), mechanical CAD (MCAD), electronic and electrical (ECAD), manufacturing planning and design of digital circuits.
DAC uses four basic steps used in the design and manufacture. They are the precursor to the collection of basic requirements and outlines the basic idea. The design uses the detailed modeling of components and modeling of the Assembly. The development makes use of technical drawings. The design of the tool is used in the production phase.
Computer Aided Manufacturing (CAM), CAD / CAM applications, scanners, CAD, CAD tools, and software such as computer-aided design for all techniques can be developed quickly and easily. general-purpose CAD software, 3D rendering software, CAD / CAM software, facilities management CAD, architecture CAD, CAD software for solid modeling and mechanical CAD (MCAD), the main applications computer software used.
