In order to improve the application efficiency of MBD model file design information in design production, the application of interactive MBD data management is studied. Based on the actual processing and production requirements and the digital and modular characteristics of CATIA platform, the MBD information model is established. Component Application Architecture (CAA) and Visual Studio are used to carry out secondary development of CATIA. After traversing the structure tree of model file, exporting MBD data of model file, a set of MBD model data information system based on CATIA platform was constructed, the data extraction of assembly model output by CATIA software was realized, and the interactive application of MBD integrated design and manufacturing on CATIA platform was completed. Through the data extraction and management of the UAV assembly file created by CATIA, the results show that the system has a positive significance for the application of MBD model for design and production.
