Introduction

TopExp_Explorer is a class in the Open CASCADE Technology (OCCT) library that provides a way to explore the topology of the shape. This is defined in the TopExp package which includes a collection of tools for exploring the topological structure of shapes in OCCT.

Example

Here is an example of how to use the TopExp_Explorer class.

#include <TopExp_Explorer.hxx>

TopoDS_Shape shape;                                         // shape to be explored

TopExp_Explorer exp(shape, TopAbs_ShapeEnum::TopAbs_FACE);  // initialize the iterator

for (; exp.More(); exp.Next())

{

    const TopoDS_Face& face = TopoDS::Face( exp.Current()); // get the value

}
