The subtraction and realization of the sculptured surfaces with AutoCAD

Abstract

在AutoCAD中,实体用了边界模型来表示.因此可以利用各种遍历器对实体的边界曲面进行数据提取,在数控加工中,主要是对实体的曲面进行分析,因此需要对实体曲面数据进行提取. In the AutoCAD, solid can by expressed by its boundary, so that we can fetch the data of the boundary surface of any solid. In the NC machining, we must analysis the information of the surface of the solid, and abstract the data of the boundary.
