CHANGE MANAGEMENT METHOD FOR THREE-DIMENSIONAL CAD DATA, AND THREE-DIMENSIONAL CAD DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a three-dimensional CAD device automating the indication of a change part and markedly reducing arrangement errors of parts for a design change after once deciding a drawing or ordering the parts of a product.;SOLUTION: This three-dimensional CAD device is provided with three- dimensional CAD information decoding software 6 for creating an assembly-parts list which covers the following hierarchies of a three-dimensional CAD model of hierarchical structure, in response to the input from an input device 1 and taking out change management information on assemblies and parts in the assembly-parts list; and difference determining software 7 for comparing the taken-out change management information and former change management information to determine whether changes are made on every assembly and every part, and displaying the determined result on a display device 2.;COPYRIGHT: (C)2002,JPO
