Principal authors: U. Kroszynski, B. Palstr9Sm 1.1 The evolution of
concepts and specifications for CAD data exchange The CAD/CAM
community has witnessed, during the last decade, the appearance of
several specifications as well as proposals for standards which
either attempt to cover wider areas or to be more reliable and
stable than the others. With the rapid evolution of both hardware
and software, the capabilities offered by CAD systems and CAD based
application systems are far more advanced than they were only ten
years ago, even when they are now based on micro-computers or
personal comput ers. The situation with standards, however, is not
and cannot be so. In order to be reliable and accepted by a wide
community of both vendors and users, a standard has to be sta ble.
This implies a life span of at least a decade. This also implies
that the standard has to be general and flexible enough to
accommodate present as well as expected future developments. 1.1.1
IGES The initial development of concepts for CAD data exchange is
strongly influenced by the US Integrated Computer Aided
Manufacturing (ICAM) programme, that dealt with the development of
methods for data exchange. In September 1979, a subgroup was estab
lished with participation of the National Bureau of Standards, the
General Electric Com pany, and the Boeing Company. The result of
this effort was the Initial Graphics Exchange Specification (IGES)
that was published as a NBS report [61] in 1980.
