Clean in U, V	These options control the directions in which to clean. You can toggle these options to clean only in U, only in V, or both.
U, V Tolerance	The allowable error for resampling the surface. Higher values produce fewer control points but reproduce the original shape less accurately. A value of zero produces no change. You can set separate tolerances for U and V independently.
