Failed to insertaddpoints

[LijieJia]

When I use the tetrahedralize and set insertaddpoint True,it didn't auto-search my .a.node file and insert the additional points to mesh.The points in the .a.node file should be the vertices of the tetrahedron inside the mesh, right?or it just add the points that near the surface of mesh.

I have already try it by c++ it truely that can build tetrahedron by using inserted the additional points,but why I set insertaddpoint True it dosen't happen as in c++
