Abstract: The main problems existing in the practical application of the existing three-dimensional drawing technology are analyzed. The design view, model and annotation partition display, integration annotation and other specific methods are proposed to solve the key problems such as lacking of clarity of three-dimensional drawings information and the definition of complex product information. In combination with the requirements of product information expression and data consistency in the digital environment, the relationship between geometry and non-geometry information is guaranteed by using the information structure tree. The detailed design scheme of the three-dimensional drawing system and the concrete realization method of the corresponding visualization function are given, and the three-dimensional drawing software system development based on ACIS and HOOPS joint platform is realized. In the three-dimensional drawing software system, the precision design of typical parts is realized, and the practicability of the system is verified.

Key words: MBD technology, three-dimensional drawings, design view, integration annotation, system development
