B-spline surfaces are piecewisely defined surfaces where the section points of the domain of definition are called knots. In 2 the authors proved some theorems in terms of knot modification of B-spline curves. Here we generalize these results for one- and two-parameter family of surfaces. An additional result concerning a higher order contact of these surfaces and an envelope is also proved.
