Surface Direction

Select U to reverse the CVs along the U parametric direction. U is the default surface direction.

Select V to reverse the CVs along the V parametric direction.

Select Swap to exchange U and V parameterization. Selecting an item a second time using the same direction restores the original CV sequence. Reversing the sequence of CVs for a surface reverses the surface normals.

Select Both to reverse the CVs and normals along both U and V parametric directions.

Keep Original

Turn Keep Original on to keep the original curves after reversing the surface.
