Computer Aided Design
Computer Aided Design (CAD) has taken the place
of drafting boards and pencils. CAD software is
many times faster than traditional drafting
methods. Mistakes can be fixed and changes can
be made quickly and easily instead of starting
from scratch. CAD software enables a designer to
design in 3-D and make virtual prototypes. Parts
can be assembled and tests can be made on the
computer instead of testing costly prototypes.
CAD is a very useful tool for communicating ideas
to people. Designs can be e-mailed to clients or
other members of a design team. Prototypes can
be easily made by sending the designs to a CNC
machine or a Rapid Prototyping machine. Many
different job fields use Computer Aided Design.
