Rhino3dm edge list not implemented?

dadandroid · April 19, 2022, 3:38pm

hi @stevebaer. I’m not able to iterate throught the brepedges of an brepedgelist in rhino3dm.py.
The following simple code produces an None:

    for e in brep.Edges:
        print(e)

I suppose hat not been implemented yet? Would it be possible to?

It should be implemented, but it doesn’t look like it is iterable yet

mcneel/rhino3dm/blob/main/src/bindings/bnd_brep.cpp#L323

      
        
            py::class_<BND_BrepFaceList>(m, "BrepFaceList")
              .def("__len__", &BND_BrepFaceList::Count)
              .def("__getitem__", &BND_BrepFaceList::GetFace)
              ;
            
            
py::class_<BND_BrepSurfaceList>(m, "BrepSurfaceList")
              .def("__len__", &BND_BrepSurfaceList::Count)
              .def("__getitem__", &BND_BrepSurfaceList::GetSurface)
              ;
            
            
py::class_<BND_BrepEdgeList>(m, "BrepEdgeList")
              .def("__len__", &BND_BrepEdgeList::Count)
              .def("__getitem__", &BND_BrepEdgeList::GetEdge)
              ;
            
            
py::class_<BND_Brep, BND_GeometryBase>(m, "Brep")
              .def(py::init<>())
              .def_static("CreateFromMesh", &BND_Brep::CreateFromMesh, py::arg("mesh"), py::arg("trimedTriangles"))
              .def_static("CreateFromBox", &BND_Brep::CreateFromBox, py::arg("box"))
              .def_static("CreateFromBox", &BND_Brep::CreateFromBox2, py::arg("box"))
              .def_static("CreateFromCylinder", &BND_Brep::CreateFromCylinder, py::arg("cylinder"), py::arg("capBottom"), py::arg("capTop"))

What do you get if you go with

for i in range(len(brep.Edges)):
  e = brep.Edges[i]
  print (e)
