Planarizes surface hulls.
Single – Affects a single CV row.
If this option is selected, holding down the key lets you select hull lines on several different surfaces and flatten them all onto the same plane.
All U – Affects all CV rows in U direction (except possibly the first and last).
All V – Affects all CV rows in V direction (except possibly the first and last).
U and V – Affects all CV rows in both U and V directions (except possibly the first and last).
For the last three settings, the first and last rows of CVs are only planarized if Include Edges is turned on.
This option determines the direction of projection for each CV.
Adaptive – The direction of projection is along the hull line that is closest to the perpendicular of the plane.
Closest point – The direction of projection is perpendicular to the plane.
Closest boundary – The direction of projection is along the hull line toward the closest surface boundary.
