NEW DIMENSIONS IN MAN-MACHINE COMMUNICATIONS

The user workstation is an important part of any CAD/CAM system with regard to: repertoire of graphic form and quality, capacities in information mapping and exchange, speed of modification and retrieval of information, ease of programming and maintenance, modularity in systems architecture, flexibility in user dialog and environment, and expandability in local processing power. Workstations employing interactive graphic displays of various principles and makes have been designed to suit the available hardware features rather than the user needs. Storage and modified storage tubes (enabling limited refresh) and faster displays are prohibitive concerning interactions. This is particularly true for intelligent 3D dialogs. The design, manufacture and steel design applications of a graphic design terminal with certain novel features in both hardware and software are presented. Direct information mapping between the user, the display processor and the applications database allow very fast and easy relational manipulations to be performed. Particular emphasis is placed on the display memory controller and the so-called hit mechanism and software modules that support features such as interpretation of a powerful high level design language, macro expansion, menu handling screen administration, device handling, picture handling, transformations, graphic elements and interactions, to cover the needs of CAD/CAM applications and many more.
