Abstract: The integration of product design and engineering analysis is the key to obtain high quality design products， the information during the integration process has been divided into three abstracted models， the CAD product design model， CAE analysis model and CAE discretized model and based on the STEP， the Design Analysis Integrated Model(DAIM) resulted from the 3 models was introducted. As last， the implementation of DAIM was presented. It should be pointed out that DAIM include the information not only from design， but also from several numerical calculations.

Key words: CAD, CAE, CIMS, DAIM
