摘要
介绍了一种基于AutoCAD的Notification 机制的面向对象的参数化方法。此方法将所有的实体细分为简单的标准对象并为各对象建立相应的反应器。反应器分为两种: 形状约束反应器和位置约束反应器。前者影响标准的几何形状; 后者影响对象的位置。通过Notification 机制, 当一个对象的尺寸被改变的时候, 通知器将通知对应的实体和其它相关的对象, 以实现尺寸驱动的参数化设计。此方法应用于模具CAD系统的软件开发中, 收到了较好的效果。
In this paper,an object\|oriented method of parametrization based on the AutoCAD's Notification Mechanism is presented.This Method divides all entities into small standard objects and creates reactors for each standard object.There are two kinds of reactors:shape restraint reactor,which affects the shape of a standard object,and location restraint reactor,which affects the location of standard objects.Through Notification Mechanism,when one object's dimension is changed,the notifier will relay the event to the object and other associated objects to realize dimension\|driven design.
