<p>A teamwork CAD system which enables each designer to refer to the latest information on another part which has a relationship to the part under his control. A part shape data base stores the data on the shape of each part and a part control data base registers the designer who is designing or modifying each part and the designer who is referring to the part. A plurality of data processing units are allotted to a plurality of designers who are designing in parallel the parts of the object. When a designer (e.g., b) modifies the part Y under his control, the nature of the modification are transmitted to the part shape data base and the fact that modification has taken place and the nature thereof are transmitted to the terminal data processing unit of the designer (e.g., a) who is referring to the part Y. The latest shape of the part Y is then displayed on the display unit of the designer a in approximate real time, so that the designer a can design the part X under his control with reference to the modified part Y. <IMAGE></p> |
