    Hold down CTRL, click on the Eraser tool and erase the lines that you see on the top and the bottom so the surface is 'smooth'.

    Create another set of arcs. They will be 'bending' a different way from the original ones. When creating the copy, note the green line connecting them. That indicates that they are on the same plane as one another and the green axes.

    You may need to use the Push/pull tool to make it so.

    Do not erase the lines that are left on the original surface from the second surface.
