TEAMWORK CAD SYSTEM AND PROCESS FOR TEAMWORK DESIGNING

摘要

A teamwork CAD system which enables each designer torefer to the latest information on another part which has arelationship to the part under his control. A part shapedata base stores the data on the shape of each part anda part control data base registers the designer who isdesigning or modifying each part and the designer who isreferring to the part. A plurality of data processing unitsare allotted to a plurality of designers who are designingin parallel the parts of the object. When a designer (e.g.,b) modifies the part Y under his control, the nature of themodification are transmitted to the part shape data base andthe fact that modification has taken place and the naturethereof are transmitted to the terminal data processing unitof the designer (e.g., a) who is referring to the part Y.The latest shape of the part Y is then displayed on thedisplay unit of the designer a in approximate real time, sothat the designer a can design the part X under his controlwith reference to the modified part Y.
