Hi Alan -

We meet again ;-)

I will be interested to hear how you get on - strikes me that generating an
outline from Gerber is potentially non-trivial. Would love to make use of
any results you generate though!

Am also looking at the possibility of using DXF track layout output &
importing that into Dolphin, then treating the tracks as a series of
"islands" for an area clear. Might just work, depending on how smart
Dolphin proves to be, but doing it that way may prove rather (mill) time
consuming compared with the outline approach. Waiting for the CD to
arrive... <sound of drumming fingers...>

Regards,
Tony
