This node defines a NURBS curve that is derived from a NURBS surface isoparm. The isoparm is defined by the "isoparmValue" and "isoparmDirection" attributes. If the direction is "U", then the isoparm is along the U direction, ie. V = isoParmValue. If the direction is "V", then the isoparm is along the V direction, ie. U = isoparmValue.

You can query the minValueU, minValueV, maxValueU, maxValueV attributes of the input surface to determine the minimum and maximum parameter values of the surface.

True means use a relative parameter range for values, from 0.0 to 1.0. Otherwise, the parameter values are absolute values.
