|| Sets the objective of the tool.
- Single Curve — Extract a curve that has a constant parametric u-value (iso-curve in the u-direction) or constant parametric v-value (iso-curve in the v-direction). The u-value or v-value is the specified Iso Value. The u-direction is the direction in which the data points that defined each row were entered; the v-direction is the direction in which the columns were defined.
- Multiple Curves — Extract a set of curves that are spaced evenly on the surface in both directions.
|| (Extract set to Single Curve only) If on, sets the iso value of the extracted curve.
|| (Extract set to Multiple Curves only) Sets the number of curves to extract from both parametric u- and v- directions.
|Ignore Trim Region(s)
|| (Extract set to Multiple Curves only) If on, the curves are trimmed by the B-spline trim curves, if any.
