Script creates a surface on the same network of points that was used in the previous script Crt_Nurbzs_Arch Izo 0. Creates bicubic NURBzS a surface with an option of isogeometrical definiteness, equal 2. Forms a interpolated network of points on the constructed surface. The form of a interpolated network shows geometrical definiteness NURBzS of a surface on a horizontal projection. The option of geometrical definiteness equal 2 is recommended to be used for strict geometrical definiteness of surfaces of 1-st order of smoothness on networks of points with rectilinear forming networks, flat sites of a network. Provides strict geometrical definiteness, exact approximation through points and 1-st order of smoothness. Generally the network of v-curves created on a network of points, is not kept in a surface.
