Direct Two-way Interface of ParaSolid and ACIS Based on Boundary Representation

Abstract

Abstract: A data exchange method for CAD systems is proposed based on boundary representation(b-rep). Considering that ParaSolid and ACIS are the two major geometry cores of present CAD softwares, the proposed method discusses how to extrude the Breps of ParaSolid and ACIS, and how to construct the map between the Breps, and rebuilds the Brep to finish data exchange. Examples are given to validate the method.

摘要： 提出了一种以边界表达Brep作为CAD软件间数据交流接口层的方法。针对目前ParaSolid和ACIS作为主流CAD几何核心这一事实，讨论了如何提取这两大几何核心的Brep，以及如何建立它们之间映射关系，继而通过重构Brep完成接口转换，并给出了实例验证该方法的可行性。
