Hi Willy,

  Hah!  RTFM!  *The book* "LEGO Software Power Tools" makes it clear that
LS00.DAT is the only constraint associated with hoses.  Sorry, just in a good
mood, because I just finished up rewriting the band synthesis code and made it
much more robust.

  LS00.DAT is needed as a constraint.
  LS30.DAT is to be used by CAD users for the thick end of a fiber optic cable,
but not as a synthesis constraint.
  LS40.DAT is to be used by CAD users for Flex Axle end, but not as a synthesis
constraint.

These unoffical parts are used by the tube synthesis process:

  STRING.DAT (from Larry)
  LS20.DAT   (pneumatic hose)
  LS21.DAT
  LS10.DAT   (exectric cable cross section)
  LS32.DAT   (small fiber optic cable end
