graphics are widely used by high-technology companies. The
high-function equipment (for example, the IBM 3250 Graphics Display
System or the IBM 5080 Graphics System) needed to view or print the
drawings is usually confined to a particular department of an organization.
For people outside that department who frequently need access to the
drawings for short-term viewing, this can be a problem. Now, with a
3270-PC /G or /GX work station and GDDM, these "outsiders" can view the
drawings in their own departments and, if necessary, produce printed copies
on a locally-attached printer. They can also use their work stations to
alter, annotate, and print other versions of the original pictures.
CAD/CAM, Computer Aided Design/Computer Aided Manufacture, is a system
whereby engineering drawings are created on high-function graphics
terminals, and held and updated on a computer data base. They can finally be
passed to computer-controlled machine tools for manufacture.
