Ken Allegro is capable of providing a 274X output from Rev 11 on. It does, at least in our case, split some layers into several layers and the Fab shop we've used recently has asked us to send them only the 274D output as they have a difficult time "remarrying" the artworks. See the DesignCouncil or Technet Oct/98 Archives for an explaination from a Cadence AE concerning this. Queries/complaints from users about this are also buried in the archives somewhere previous to this.
