Another KiCad question

Hi all...
Can anyone tell me how to add a simple single Plated Through Hole for adding wire leads to a PCB created with KiCad 7.0.2? I assume that like any other component it must be added to the schematic first, then the PCB. I've searched and can't find what I'm looking for.

I'd use a connector with a single pin in the schematic and a footprint with the hole that you need. It's generally good practice to have the test points and connectors indicated on the schematic anyway.

Connector_Generic -> Conn_01x01 would be my choice for the schematic symbol.
Connector_Wire -> SolderWire-* has a bunch of different PCB footprints for wires, including the single hole you're looking for.

I found the generic single pin connector and then modified a resistor footprint to associate with it, and at first it seemed to work, but when I saved and reopened it the footprints were gone.
Well I figured out that I hadn't saved it properly to the library...oh well, live and learn.

If you don't want to represent them in the schematic, you can either lock the footprint, or check the "Not in shcematic" checkbox in the Footprint Properties dialog. Either one will keep doing an Update from Schematic from deleting the footprint.
 
You need to add any custom footprint to a library. I suggest creating your own custom library for this.

The best practice is to have the schematic match the layout. So if you want a hole for a wire in the layout you add a connector on the schematic. Sure. You can choose to check the "not in schematic" box, but that's not the recommended workflow. I would only use that for mechanical components such as mounting holes and vent holes.
