摘要 如何更好地表示三维实体的几何模型,是CAD/CA M中的首要问题。本文提出的混合模型结构既能完整、精确地表示几何模型,又充分考虑了适应特征造型的发展,便于 CAD/CAM的集成。改进的翼边结构能够完整无二义性地定义几何实体,方便快捷地访问相关数据,从根本上保证了 CAD/CAM系统的稳定性及可扩展性。 In CAD/CAM, it is the cardinal problem to give a good depletion about geometry modeling of 3D objects. In this paper,we expound a new mixed modeling structure. It is not only can describe a geometry modeling completely and precisely, but also make CAD/CAM very easy to integrate which are fit for the development of feature modeling. The mordified winged edge data structure can modify a geometry object in completely and no - double - meaning, also can visited relative datum expediency and quickly. All of these can make CAD/CAM system have more stability and high expanding feature.
