Here is a case that I thought had been fixed in the latest SR Rhino 5, but no!
On the edge of the red color, blend edge and the chamfer edge work, but without considering that it is a solid operation.
The shelling of one of the flat faces of the solid does not give a correct result (in particular in correspondence of the face curve tangent).
Check it out, and if possible, in the case where it was a limit of Rhino, propose an improvement of these situations.
