Anything that is on - or forms an integral part of - the PCB **must** have a **PCB Footprint** defined for it in the library. In order for the correct PCB Footprint to be pulled in to a PCB on first converting a Schematic to PCB (by pressing the **Convert to PCB...** button) or when updating the PCB from the Schematic (by pressing the **Update PCB...** button in the Schematic Editor or the **Import Changes...** button in the PCB Editor) then the component **must** be represented in the Schematic by a corresponding **Schematic Symbol**. The relevant symbol **must** have the name of the relevant PCB Footprint assigned to its **Package** attribute and the **pins** of the symbol **must** be correctly mapped onto the **pads** of the footprint. So if you want to include for example a mounting hole, a surface mount test point or a connection for a wire soldered straight onto the PCB then you must first find or create a suitable **PCB Footprint**. You can find an existing footprint and note the **name** or you can create your own, uniquely **name** it, check it and save it. For a hole or a test point you will find many suitable symbols in the library whilst for simple wire connection you could use a single pin header Then you must find or create a suitable **Schematic Symbol** and assign the **name** of the suitable PCB Footprint identified above to the **Package** attribute of the **Schematic Symbol**. You can find an existing symbol or you can create your own, uniquely **name** it, check it, save it and then use that in your schematic. For a hole or a test point you will find many suitable symbols in the library whilst for a simple wire connection you could place a symbol for a single pin header.

@Andy I've seen you give some version of this answer in multiple threads where people ask the same question.  I guess: why doesn't easyeda just create a "pad" component in the schematic designer?  Clearly people want this functionality.
