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 ed 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. The following slides show some examples.

Mechanical Engineering

Cartography (Map Making)

Marine Engineering

Interior Design

Electrical Engineering

Aviation

Automotive

Architecture
