Hi guys, I’m afraid illness kept me away so I have only just come back to this.
Thanks for the answers, I need to try the suggestions mentioned above, it looks like there may be a way through.
In the meantime I have attached a DXF file renamed with the .FZP extension as requested. The file is just an exemplar one, the red is for cutouts and holes, the white / black is the outline of the ‘wiring’ (what is the proper name for the copper lines between two contacts?). As you can see it is very low density, so I imagine I can improve that
Interested to see what I can do with it
