class CurvPointRadInv from BRepBlend
inherits CurvPointFuncInv from Blend
---Purpose: Function of reframing between a point and a curve.
-- valid in cases of constant and progressive radius.
-- This function is used to find a solution on a done
-- point of the curve 1 when using RstRstConsRad or
-- CSConstRad...
-- The vector used in Value, Values and Derivatives
-- methods has to be the vector of the parametric
-- coordinates w, U where w is the parameter on the
-- guide line, U are the parametric coordinates of a
-- point on the partner curve 2.
