17 class SurfCurvEvolRadInv from BRepBlend
19 inherits SurfCurvFuncInv from Blend
21 ---Purpose: Function of reframing between a surface restriction
22 -- of the surface and a curve.
23 -- Class used to compute a solution of the
24 -- surfRstConstRad problem on a done restriction of the
26 -- The vector <X> used in Value, Values and Derivatives
27 -- methods has to be the vector of the parametric
28 -- coordinates wguide, wcurv, wrst where wguide is the
29 -- parameter on the guide line, wcurv is the parameter on
30 -- the curve, wrst is the parameter on the restriction on
