WebIntroduction. TopoDS_Iterator is a class in the Open CASCADE Technology (OCCT) library for iterating over the sub-shapes of a given shape in a topological hierarchy. This is a part of … Web摘要Abstract：本文简要介绍了几何造型中的边界表示法（BRep），并结合程序说明OpenCascade中的边界表示的具体实现，即拓朴与几何的联系。对具有几何信息的拓朴结构顶点（vertex）、边（edge）、面（face）进行了详细说明。本文只对顶点数据进行说明。

Lets take the example that the user picks Face9 in a Pad as the UpToFace of a pocket whose support is the Pad. The ShapeHistory of "this" (the Pad) is used to find the parent of Face9. In the simplest case this will be an edge of the sketch of ... modular homes lehigh valley pa
