Blend_SurfRstFunction. //! //! Thus this pseudo path necessitates 3 criteria of regrouping : //! //! 1) exit of the domain of the curve //! //! 2) exit of the domain of the surface //! //! 3) stall as there is a solution to the problem //! surf/surf within the domain of the surface //! of support of the restriction. //! //! Construction of a BRepBlend_Line between a surface and //! a pcurve on surface from an approached //! starting solution. The output entries of this builder //! are of the same nature as of the traditional walking //! but the requirements on the Line are not the same //!
