Excellent Tig, thanks, it's nice to know you will look at it.
I'm at sea again for a while but will get back home eventually and I'll sort out the best exports for what I do. Off the top of my head I know .dwg work for my plotter, not sure of the file format for the laser cutter, don't actually have it in hand yet, but it will be capable of cutting 900mm wide by 2000mm long.
In the meanwhile, if anyone else sees the benefits and knows the format they need.......
Sorry, hate using a phone for this stuff, typing is a pain, and satellite connection is so hit and miss.
