If a footprint has non-circular plated through-holes (ex: slots), we export them as board cutouts. If you follow the instructions above, these cutouts will appear on Mechanical Layer 1. When manufacturing your design, please ensure that you send gerber files for Mechanical Layer 1 to your PCB manufacturer.
The footprint I'm using in Altium has board cutouts. Why? What layer are they on?
