Abstract: 3D CAD software is the core and foundation of the whole industrial software system. However, the high-end 3D CAD software market in China is currently monopolized by foreign industrial giants while the share of domestic 3D CAD software in the middle market is also very low, which seriously threatens the security of our industrial system. In order to explore the development trends of 3D CAD and propose a feasible path for the high-quality development of domestic 3D CAD software, the research progress of 3D CAD key technologies such as 3D geometric modeling engine, solution of geometric constraints, CAD data exchange, CAD interface and secondary development, integration of product information, processing of design knowledge, large-scale assembly, model-based definition and so on are systematically reviewed, the technical challenges and development directions of which are also discussed. The development status of domestic and foreign 3D CAD software is investigated comprehensively and thoroughly, based on which the gap between domestic and foreign 3D CAD software as well as the underlying causes is analyzed. The development trends including integration, intelligentization, cloudification, professionalization and unification of 3D CAD software are expounded. And finally, some suggestions on the realization of high-quality development of domestic 3D CAD software are given.

Key words: 3D CAD, integration, intelligentization, cloudification, professionalization, unification
