Then I met trouble for 3d case. Now "edge of mesh" is 1d and "face of mesh" is
2d. My understanding is now only surface projection is required and line
projection is meaningless. However I keep run into error that "point is not on
manifold" even tolerance is 100000 times of original iges tolerance.
In 3d, we first refine the edges and then the faces. You need manifolds for
both 1d and 2d objects.
