【摘要】 通过论述与流程图相结合的方式 ,对面向方案CAD软件进行了探讨。在分析工程设计流程、工程设计的一般特点的基础上 ,将面向方案思想引入CAD领域 ,给出了面向方案CAD软件的概念和面向方案的基本指导思想。进一步探讨了面向方案CAD软件应具有的基本特征 :能提供一整套的供用户建立设计方案的手段 ;能提供对设计方案合理性、可行性进行检测的手段 ;能提供给设计人员进行方案对比优选的“方案优选”平台 ;能够将用户的设计方案的信息完整地存储在计算机里 ,并提供将设计方案向工程图纸转化的手段 ;为方案修改提供一定环境。对于面向方案CAD软件结构中的五大基本模块 :数据库模块、知识管理模块、计算模块、绘图模块和主控模块 ,并简要地论述了各模块的任务与功能。更多还原

【Abstract】 The project-oriented CAD software is discussed with the flow chart in flow designer and engineering designer. Based on their characters, the project-oriented idea is used in CAD realm and the fundamental thought is given. Furthermore the characters of the project-oriented CAD software are discussed. It can offer a set of methods for user to design; it can inspect the designer’s rationality and feasibility; it can save the user’s design information in computer and the design scheme can be changed into the production drawing. The project-oriented CAD software is made up of five modules: database module, knowledge management module, compute module, drawing module, main control module. In the paper, the function and mission of each module are introduced briefly.更多还原
