Many
thanks to Phil, Ahne, Tom and Steve for the fast replies to
this.
Some
good information about gerber / aperture files in there as
well.
(I've
actually used an old vector plotter in the past - almost remember how to load
the tape drive and initialise..)
I've
tried loading it as an 'Eagle' file with no success.
Unfortunately, I don't have the option in Camtastic to
load it in the Dassault Systemes format.
Looking at the file using wordpad, it is quite
readable, and it may be that the board fabricator may be able to use this to
manually edit the aperture list within their own CAM
program.
regards,
Phil.
