I’m trying to design a custom through-hole footprint for a large circular pin that has flats milled onto two sides (for a spanner/wrench to hold the pin whilst a nut is fixed on it).
Is there a way to make this cutout in a footprint? I’ve been looking at the new “Custom Shape Primitives” in Pad Properties but can’t see how to use those for the hole rather than just the pad.
My initial reaction would be to put a pad on both top and bottom layers (2-layer PCB) in the footprint, and then use edge cuts to create the correct shape hole in the layout, and then tell the fab-house that I want the hole plated, but that seems a bit hacky!
The image shows what I’m trying to achieve. It looks similar to a slot, but the corners need to be sharper (although they can have a 1mm fillet on them as the drill will need that).
