CAD may be used to design curves
and figures in two-dimensional
("2D") space; or curves, surfaces,
and solids in three-dimensional
CAD is an important industrial art
extensively used in many other
design applications, including
automotive, shipbuilding, and
aerospace, industrial and
architectural design, prosthetics,
CAD has become an especially
important technology within the
scope of computer-aided
technologies, with benefits such as
lower product development costs and
a greatly shortened design cycle.
designers to lay out and develop
work on screen, print it out and
save it for future editing, saving
time on their drawings.
CAD is also widely used to
produce computer animation for
special effects in movies,
advertising and technical manuals.
The modern ubiquity and power of
computers means that even perfume
bottles and shampoo dispensers are
designed using techniques unheard of
by engineers of the 1960s. Because
of its enormous economic importance,
CAD has been a major driving force
for research in computational

hardware and software), and discrete
The design of geometric models for
object shapes, in particular, is
often called computer-aided
geometric design (CAGD).
CAD is clearly important to
members of the fashion industry.
