二维环境下参数化特征设计的研究

Study of Parametric Design Based Feature in 2D Environment

针对参数化特征设计 ,研究了特征的分类及其在二维环境下的投影 ,进而给出二维环境下用户可扩充的特征库。其中的特征是参数化定义的 ,视图中的投影是相互联系的 ,对一个视图的修改 ,将导致其余视图的相应变动 ,从而实现尺寸驱动的参数化特征设计。

The classification and projections of feature are studied for parametric design based feature;extensible feature library is further given in 2D environment.The feature is defined parametrically.The projections in views are interrelated.The modification of one view can bring another view corresponding modifications.In this way,the dimension driving parametric design based feature is realized.
