So I am modeling a NURBS head now, and as I was working on the nose structure, I noticed a little seam or almost crease in the smooth shading down the side of the nostel. I put it in wireframe and looked a little closer to find that there were 2 Isoparms squeezed side by side. I have no idea how it got there because I did not add any Isoparms in that surface direction and the surface was made from boundry curves.
Is there any way I can delete one of those Isoparms?
