The demand for technology to aid sharing product information between digital manufacturing and C3P (CAD, CAE, CAI, PDM) systems has increased along with the technological development of computers and networks. Although usage of these systems has risen, system integration is difficult in practice because of the heterogeneous characteristics of the systems. In order to resolve this problem, the design of a CAD/CAE/CAI verification system is required to develop a Web-based PDM system, which would allow for wider verification of engineering data within the Web environment. In this paper, a CAD/CAE/CAI verification system interfaced with a Web-based PDM is presented to examine CAD, CAE, and measurement data. For the integration of CAD/CAE/CAI systems and a PDM system, the CAD and CAE translators were interfaced and an integrated verification system was constructed on the basis of the verification kernels. By applying the integrated CAD/CAE/CAI verification system toward actual automobile design processes, the effectiveness of the CAD/CAE/CAI verification system has been successfully verified.
