Hi, I asked Aisler to produce PCB from the attached design. All is good except that 3 holes are missing, namely the GND connectors of KY-012 and KY-019 parts. All other expected holes are present (whether they are round or square). I compared the properties in the Inspector, and part editor, and I fail to understand why those holes are missing, the connectors are all described the same way. E.g. when I compare the properties of the arduino nano D1/TX pad and of the KY-019 GND part, they look the same, but the first has a hole drilled on the PCB, the latter has not. I managed to drill the holes myself and solder the connections to the bottom layer. However where is my mistake in the design ? Thanks for your help, J.

Always check gerbers before you get stuff made, ie, those holes in your sketch don’t exist in real life. Those parts are made wrong, they need a ring pad on top of the square pad. ---

Thanks OldGrey for your answer. I thought the problem was in my design since I assumed the .fzpz for those parts were correct. I reported the problem where I found the .fzpz files ([https://arduinomodules.info/ky-019-5v-relay-module/](https://arduinomodules.info/ky-019-5v-relay-module/)). ---

I suspect the part supplier may not know how to fix this (the problem is that the gerber processing code doesn’t handle holes in anything but a circle path.) Below are corrected versions of both parts with the path replaced by a circle and a square which will produce a hole. They are welcome to use the parts on their site so we get working parts out there.
