DEVICE, METHOD AND PROGRAM FOR CAD DATA IDENTITY VERIFICATION

摘要

PROBLEM TO BE SOLVED: To verify identity of CAD data including semantic information. SOLUTION: The CAD data as a target of identity verification is constituted using graphical data defining a feature and attribute data defining attribute information. The feature and the attribute information are correlated by identification numbers and the semantic information can be added to the feature. This device verifies the identity of two CAD data with such a structure. The device first makes the feature correspond in the two CAD data, and then makes the attribute information of each feature correspond from the feature's correspondence. Then, the device verifies the identity of the CAD data including the semantic information by verifying the identity of the corresponding attribute information. COPYRIGHT: (C)2007,JPO&INPIT
