Summary:
Computer Aided Design (CAD) is a form of software automation that uses
various computer-aided design tools that helps engineers, architects and
other professionals in the design activity purposes. It is considered to
be both software and special-purpose hardware. In product lifecycle
management, the use of geometric tools plays a significant role. The CAD
is available in various packages ranging from 2D vector based drafting
systems to 3D parametric surface and solid design modelers.


Keywords:

Computer Aided Design (CAD) is a form of software automation that uses
various computer-aided design tools that helps engineers, architects and
other professionals in the design activity purposes. It is considered to
be both software and special-purpose hardware. In product lifecycle
management, the use of geometric tools plays a significant role. The CAD
is available in various packages ranging from 2D vector based drafting
systems to 3D parametric surface and solid design modelers.

CAD allows you to prepare fast and accurate drawings. Vir tually anything
can be constructed and built as a design model developed in the CAD
system. The flexibility to alter the drawings is performed very easily
with a minimal effort. It is also referred as Computer Aided Design and
Drafting (CADD). It is sometimes translated as computer-assisted or
computer-aided drafting. The tool provides you a better and the faster
way of developing the drawings with better creativity.

CAD is used in major areas like applications that involve computer
graphics, computer- aided manufacturing, solid modeling, solving by
constraints, architectural purpose and VLSI design. Other fields that use
the CAD are Architecture Engineering and Construction, Building
Engineering (AEC), Mechanical CAD (MCAD), Electronic and Electrical
(ECAD), manufacturing process planning, and digital circuit design.

CAD uses four basic phases that are used for designing and manufacturing.
They are the requirement phase which collects the basic requirements and
conceives the basic idea. The designing phase uses detailed component
modeling and assembly modeling. The development phase uses engineering
drawings. The tool design is used in the manufacturing phase.

Computer Aided Manufacturing (CAM), CAD/CAM applications, CAD scanners,
CAD resources, and the software used by these computer-aided techniques
all enable the drawing to be developed quickly and easily. General
purpose CAD software, 3D rendering software, CAD/CAM software, facility
management CAD, architectural CAD software, solid modeling CAD software
and Mechanical CAD (MCAD) are the major computer -aided software
applications that are used.
