In order to change the parameterization of a surface, e.g. to include a set of surfaces in a poly surface or to change the surface normal, CAESES/FFW offers a couple of functions.
For point-based surfaces like NURBS and B-Spline surfaces simply select the surface and use one of the functions that are offered in the top bar of the user interface.
For point-based surfaces this is rather simple, because the order of points can be rearranged. For other surfaces, e.g. Metasurfaces, Surfaces of Revolution or Ruled Surfaces this is not possible. For those surfaces it is necessary to add an Image Surface based on the original surface and either change the domains*, e.g. U=[1,0] rather than U=[0,1] to change the surface orientation, or toggle the swap option.
