  35
  36             This 3D primitive expands the SdrPrimitive3D to a 3D rotation definition.
  37             The given 2D PolyPolygon geometry is imagined as lying on the XY-plane in 3D
  38             and gets rotated around the Y-Axis.
  39
  40             Various possibilities e.g. for creating diagonals (edge roudings in 3D)
  41             and similar are given.
  42
  43             The decomposition will create all necessary 3D planes for visualisation.
