Bugger!

I've got the files lined up, have contacted the laser cutter who gives me the list of formats they do. Do ya think that the free sodding CAD program will save as any of them? Apparently the Alibre design software is designed to lock you into using their service unless you shell out money for the full version. Frankly I expect far better for nothing.
(Unless its just me being dumb again, in which case I apologise. Otherwise I wish you to drink nothing but Budweiser for the rest of your days).

Time for plan B.
(Mental note to self; should prepare a plan B before actually requiring it)
