Alan,
Two things! Run this past Dave Kush at:
http://www.calweb.com/users/d/dnjinca/ Also, have you played with the SCRIPTS that are in
Eagle. There is one there to turn a PCB drawing into a DXF. In
the Cad_Cam conference there used to be a script that made
a PCB drawing into GCode. I only played with the DXF one. I
abandoned Eagle because of the Traveling Salseman Syndrome.
Someone showed me how to use ACE to fix my drawing. I think
you use Vector.
