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.

Attributes (5)

inputSurface, maxValue, minValue, outputCurve, relative

Long name (short name) Type Default Flags
inputSurface (is) nurbsSurface NULL outputinputconnectable
The input surface
minValue (min) double 1.0 outputinputconnectablestorablekeyable
Minimum parameter value for the curve segment If relative is true, then this attribute has minimum value of 0.0.
maxValue (max) double -1.0 outputinputconnectablestorablekeyable
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.
relative (r) bool false outputinputconnectablestorable
True means use a relative parameter range, from 0.0 to 1.0. Otherwise, the parameter values are absolute values.
outputCurve (oc) nurbsCurve NULL outputconnectable
The output curve
