class SurfCurvConstRadInv from BRepBlend
inherits SurfCurvFuncInv from Blend
---Purpose: Class used to compute a solution of the
-- surfRstConstRad problem on a done restriction of the
-- surface.
-- The vector used in Value, Values and Derivatives
-- methods has to be the vector of the parametric
-- coordinates wguide, wcurv, wrst where wguide is the
-- parameter on the guide line, wcurv is the parameter on
-- the curve, wrst is the parameter on the restriction on
-- the surface.
