Abstract：

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.
