Computer-Aided Design

Computer-Aided Design (CAD) is the use of computer technology to aid in the design of a product, particularly the drafting of a part or the product—a part visual (drawing) and part symbol method of communications particular to a specific technical field. It is in origination, the use of computers to aid the art of drafting—the integral communications of technical drawings — which for a three dimensional object are typically represented by three projected views at right angles —drafting is the Industrial arts sub-discipline which underlies all involved technical endeavors. Current CAD software packages range from 2D vector base drafting systems to 3D solid and surface modellers. Modern CAD packages can also frequently allow rotations in three dimensions, allowing viewing of a designed object from any desired angle, even from the inside looking out. Some CAD software is capable of dynamic mathematic modeling, in which case it may be marketed as CADD — Computer Aided Design and Drafting.
