Computer Aided Design (CAD) allows engineers
to create detailed designs of parts with
maximum efficiency and minimal cost. The
days of the drawing boards are essentially
over with the release of affordable and
easily used 2D and 3D CAD packages. The
aim of CAD is to apply computers to both
the modeling and communication of designs.
This includes automating such tasks as the
production of drawings or diagrams and the
generation of lists of parts in a design,
and providing new techniques which give
the designer enhanced capabilities to assist
in the design process.
Computer-aided design now involves the
creation of a central design description
or model data which all applications in
design, analysis and manufacturing can utilize.
Computer-based techniques for the analysis
and simulation of the design, and for the
generation of manufacturing instructions,
are now closely integrated with the techniques
for modeling the form and structure of the
