Manufacture cutting PCB

Do something like that:

In my case:

  • distance between PCBs is 2mm,
  • holes are 0,8mm
  • in row hole center to hole center is 1.2mm
  • between rows 1.4mm
  • 4.2mm center to center of half circles (r=1mm) at Edge.Cuts
    Holes at rows ends are opened to the 2mm gap. 3D viewer not shows it correctly.

This one I made by Copy-Paste defined set of 6 holes with arcs at Edge.Cuts but later I defined a footprint for that.
