A curveFromSurface node is the basis node for curveFromSurfaceIso, curveFromSurfaceBnd, and curveFromSurfaceCos. This node describes a NURBS curve derived from a NURBS surface isoparm, boundary or curve-on-surface. The resulting NURBS curve is the attribute "outputCurve" and its extent can be controlled by the minValue and maxValue parameters. If the "relative" attribute is true, then the minValue and maxValue parameters are expressed as percent, ie. ranging from 0.0 to 1.0.

inputSurface, maxValue, minValue, outputCurve, relative

Long name (short name)TypeDefaultFlags
inputSurface (is) nurbsSurfaceNULLoutputinputconnectable
The input surface
outputCurve (oc) nurbsCurveNULLoutputconnectable
The output curve
maxValue (max) double-1.0outputinputconnectablestorablekeyable
Maximum parameter value for the curve segment. Must be greater than or equal to the minValue attribute. If relative is true, then this attribute has maximum value of 1.0.
minValue (min) double1.0outputinputconnectablestorablekeyable
Minimum parameter value for the curve segment If relative is true, then this attribute has minimum value of 0.0.
relative (r) boolfalseoutputinputconnectablestorable
True means use a relative parameter range, from 0.0 to 1.0. Otherwise, the parameter values are absolute values.
