Starting around the mid 1970s, as computer aided design systems began to
provide more capability than just an ability to reproduce manual
drafting with electronic drafting, the cost benefit for companies to
switch to CAD became apparent. The benefit of CAD systems over manual
drafting are the capabilities one often takes for granted from computer
systems today; automated generation of Bill of Material, auto layout in integrated circuits,
interference checking, and many others. Eventually CAD provided the
designer with the ability to perform engineering calculations. During
this transition, calculations were still performed either by hand or by
those individuals who could run computer programs. CAD was a
revolutionary change in the engineering industry, where draftsmen,
designers and engineering roles begin to merge. It did not eliminate
departments, as much as it merged departments and empowered draftsman,
designers and engineers. CAD is just another example of the pervasive
effect computers were beginning to have on industry. Current
computer-aided design software packages range from 2D vector-based drafting systems to 3D solid and surface
modelers. 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 mathematical modeling, in which case it may be marketed as
CAD.
