Symmetry

Hi,

Have been using "Symmetry", but find that if I want/need Nvil to Calculate symmetry, although the correct symmetry is shown (vertex > Calculate symmetry > Show Symmetry), the actual symmetry Plane(Symmetry plane visible) and any work done on the model(moving sub-object etc) always works from object Pivot point.

Maybe I am missing something? But if a tool is used to calculate symmetry, then should the symmetry plane not move to that calculated symmetry line/plane?
