How to create TopoDS_Wire from TopoDS_Edge(s) in OpenCASCADE

OCCUtils provides easy-to-use conveniece functions to convert multiple TopoDS_Edges to a TopoDS_Wire:

#include <occutils/Wire.hxx>

using namespace OCCUtils;

TopoDS_Wire& wire = Wire::FromEdges({edge1, edge2})

You can also pass a std::vector<TopoDS_Edge> to Wire::FromEdges().

If you want to do it manually without using OCCUtils, you can use BRepLib_MakeWire like this:

BRepLib_MakeWire wireMaker;
TopoDS_Wire wire = wireMaker.Wire();
