Most current virtual maintenance systems are independent of CAD systems and the results in modification, maintainability analysis and evaluation can not be shared by CAD systems automatically and directly, reducing design efficiency and making information silo. The approach integrating virtual reality function into CAD system is adopted to build product information model of virtual maintenance integrated into CAD System (VM-CADPIM) by extending CAD product information model and making it virtual maintenance system a part of CAD system. A virtual maintenance system integrated into CATIA seamlessly is developed based on the VM-CADPIM to implement the bidirectional information transmission between virtual maintenance system and CAD system. The correctness and effectiveness of the information model in eliminating the inherent defects of virtual maintenance system independent of CAD and making virtual maintenance system more practical and significant in engineering applications are shown.
