      SUBROUTINE GTRDSE(PAR,ISHAPE)
C-
C----------------------------------------------------------
C-  Calculates the coordinates of the corner points of a GEANT  shape
C-  from the shape parameters.   The end faces are generated by drawing
C-  connected polylines between the corner points at each Z-end of the shape.
C-  A ruled solid is then defined between the 2 faces, and written out in SET.
