Reverses the parametric direction of a surface (U or V), or swaps the U and V parameters of a surface.
Reversing the U or V parameterization, or swapping the U and V parameters for a surface does not affect the direction of the normal.
All intersecting – Display the U and/or V direction of all surfaces under the cursor.
Closest to eye – Display the U and/or V direction of the nearest surface under the cursor.
Reverse U direction – Reverse the direction of the U isoparametric curves.
Reverse V direction – Reverse the direction of the V isoparametric curves.
Swap U and V direction – Swap the isoparametric curves so that the U direction becomes the V direction and vice versa.
