To resolve the problem viewing and looking for itemized manufacturing information manually in MBD (Model Based Definition) models is a heavy workload and time-consuming work in the process of production preparation, therefore the techniques of retrieval, extraction, analysis and reconstruction of non-geometric information were studied based on the storage specification in MBD models. A system of organizing and reconstructing process information for MBD models was developed, which satisfied different levels of needs for different stages, different roles and different professions in the manufacturing process.
