25 years ago, nearly every drawing produced
in the world was done with pencil or ink on paper. Minor changes meant
erasing and redrawing while major changes often meant recreating the
drawing from the scratch. If a change to one drawing affected other
documents you were dependent upon having someone manually recognize
the need to make the changes to the other drawings and to do so.
CAD has fundamentally changed the way design is done.
