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ObjectARX编程技术。阐述了通过利用AutoCAD核心数据库的开放结构和ObjectARX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 。
Think of Object-oriented design, abstract mechanism of object and technology of procedure design in ObjectARX are introduced. It elaborates process of definition special object by using of open structure of AutoCAD inner database , base class provided by ARX and mechanism of calss inheritance and derivative. It also elaborates technology of date exchange. On this base ,object models of power CAD are constructed .
