    This input  demonstrates  that  the   "drilling-milling"
    technique  available  in PLANT can be used also with BFC
    grids.  The combination of BFC  with  blocking-off  some
    cells  to fit extra geometrical features,  may bring the
    number of practical advantatges.

    In this  case  the   sphere   and   cylinder   will   be
    "drilled-out" in the beam of asteroidal cross section.

   REGION(,,,,9,20)
    The use  of  SPHERE,  XYCIRC   and   other   geometrical
    functions is similar to cartesian cases.  The difference
    is  that  arguments  must  be  specified  in  terms   of
    reference cartesian coordinate system.  The latter is of
    routine use for all BFC problems.
