CAD-Arbeitsplatzrechner

The invention relates to a process for the computer-assisted processing of CAD models, where the model data and relations are continuously requested, altered and stored during the process of model processing, and where free storage locations are processed, and where data from previously generated CAD models, which may be stored in a hard disk file, can be stored in an unprocessed model data structure for further processing. The invention is characterized by the fact that model data and relations are structured in a specific manner and substructures restricted by a start and end address are formed, and the start address together with the end address and the associated substructures are stored and called up separately. The process is implemented to great advantage on a CAD workstation computer which is fitted additionally with a functional storage system consisting of a functional access control, a structure processor, a table store, a word-organized model data store and a bus interface to couple the functional storage system to the CAD workstation computer.
