I have set up some NTPH Mechanical holes to be drilled in a footprint like this:
However in the 3D viewer they don’t show up as actual holes. You can see that there is something drilled into the PCB but it doesn’t go all the way though.
It looks like a bug but I just wanted to confirm I’m not doing something wrong. They holes appear in the drill file output so I’m sure the manufacturer will drill them right through.
