摘要
介绍了面向对象的设计思想和对象的抽象机理在电网 CAD( PWCAD)系统中的应用以及 Object ARX编程技术。阐述了通过利用 Auto CAD核心数据库的开放结构和 Object ARX提供的基类及类的继承、派生机制定义专业对象的过程以及建模系统的数据交换技术 ,并由此建立了 PWCAD的对象模型。
The application of object oriented design concept and abstract mechanism of object to power CAD system and programming technology of Object ARX were introduced. The process of defining special object made by using opening structure of Auto CAD inner database, base class provided by ARX, mechanism of class inheritance and derivative was described, as well as the technology of data exchange. Thus the object models of power CAD were established.
