I ve played with spline modelling for several years. Beazer curve controls and symmeterical in it are really nice. But, not all axis are avialable in it. I get annoyed when I find something missing in it. I submitted Eovia several times to get it fixed but they never get around to it. I also submitted Eovia for Spline Modeling programmable extensions license and they said no. I wonders when Eovia will ever get around to upgrade Spline and Vertex. Both room really need to get combined together so it can get symerical and beazer control in the vertex modeling room it would meet all my modelling necessity.
