  I've seen it but prefer real CAD/CAM systems.

  WCS is CAD/CAM & CAM.
  Fixture offsets come out of such a just a call to a numbered offset
register (or set of same) in the CNC control. CNC control then applies 
the data set by the machine's operator in it's fixture offset registers
(under program control). 
  Part of why ISO-4343 mentions "in the part coordinate system"
to begin with.
  Pretty simple but well beyond jb's conception.

  Did you catch his wanting to link the active WCS to the active view/****t
automatically? LOL ... I think you are either pretty gullible or miss most
of
his profound stupidity. Or both.

  He claimed to program using the numbers on the print & then used a
negative
diameter in his code example, etc <G>.
