摘要
针对现有三维图样技术在实际应用中存在的主要问题,提出了设计视图、模型与标注分区显示、集成标注等具体方法,解决了目前三维图样信息显示不清晰、无法满足复杂产品信息定义需求等关键问题。结合数字化环境下产品信息表达与数据一致性等需求,采用信息结构树保证了几何与非几何信息间的关联性。给出了三维图样系统的具体设计方案,以及相应可视化功能的具体实现方法,实现了基于ACIS与HOOPS联合平台的三维图样软件系统开发,在该系统中完成了典型零件的精度设计,验证了三维图样软件系统的实用性。
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.
