摘　　要：参数式CAD系统由于设计对象的复杂性和关系的多样性,导致参数管理较为复杂。该文针对定型产品的设计情况,将设计信息分为设计参数和格式信息,采用不同的存储方式和处理技术,以提高设计效率。提出了以模板文件存储图形格式信息、以数据库存储设计参数的参数式CAD系统的存储策略。并在AutoCAD环境中,探索了实现技术,给出了系统结构图。The complexity and diversity of design object in parameterized CAD system result in the complexity of parameter manage. In this paper, the product design information is divided into design parameters and styles information for the case-design situation. The design efficiency is improved by introducing different storage styles and disposal technique. So a new storage strategy that graphic styles are stored in the template file and design parameters are stored in the database is introduced. The correlative techniques are discussed and the system architecture is also presented based on AutoCAD system.
