Reason of failed review:
In drill drawing layer,here’re sometimes more drill marks than drill layer.Yet we need to confirm they’re necessary to be made as drills or cutout/slots to avoid mistake.
Suggestion:
It’s advise to design the hole or cutout/slot in drill layer,or in GKO layer or GM1 layer.PCBWay will produce the slots in GKO layer or GM1 layer by default on the PCB.
