PROBLEM TO BE SOLVED: To efficiently repair an error that a reference destination is lost, which tends to occur in importing external data, in three-dimensional CAD application having a parametric function. SOLUTION: Specific reference information destinations of relevant entities are specified by the reference relation of a model before change with respect to a shape to be generated as the result of importing the external data. Besides, coordinate and vector information using a three-dimensional CAD function is obtained with respect to the entities, thereby to specify approximate entities in a shape after replacement. The approximate entities are selected on a screen, and then, an operator is urged to perform confirmation. Thus, the reference relation is updated. COPYRIGHT: (C)2011,JPO&INPIT |
