Selects curves in the negative curve direction. SimplifyInput=Yes/No. Places point objects at curve control point. Clean up the curves so they don’t extend past the top and bottom curves. All surface creation commands in Rhino result in the same object: a NURBS surface. Simplifying ensures that NURBS curves that consist of arc and line segments are split into proper arc and line segments making the conversion to arcs and lines more accurate. Splits the curve instead of placing point objects. If the gap between two edges/curves is less than this value, the chain selection will ignore the gap and will select the next segment. Length.
