I am trying to add control points on an elliptical base of a bottle that I am modelling. I am using a 2001 version so I'm not sure that it even has this capacity. I select fillet, then in the property manager, select the edge I want to fillet, then select "variable radius". But it only shows one vertex on the elliptical base. The tutorial that I am following says that the system defaults to 3. Did this feature begin with a later version?  Is there some way that I can add control points along the edge?
