Draw a 3D circle arc.

   drawCircleArc3d([XC YC ZC R THETA PHI PSI START EXTENT])
   [XC YC ZC]  : coordinate of arc center
   R           : arc radius
   [THETA PHI] : orientation of arc normal, in degrees (theta: 0->180).
   PSI         : roll of arc (rotation of circle origin)
   START       : starting angle of arc, from arc origin, in degrees
   EXTENT      : extent of circle arc, in degrees (can be negative)
   
   Drawing options can be specified, as for the plot command.
