astrimid - quick question about thermal pad. I'...

quick question about thermal pad. I've tried to define a qfn20 package for chip, but in PCB representation I don't the the thermal pad. There's also no corner gnd pin. Am I doing something wrong or is it a missing feature?

Thinking about it more `<chip` footprint only implicitly define the pads configuration, as it represents a component mounted to PCB. So it rather defines chip pins. While the pcb pads can have a different footprint configuration. I couldn't find a way to separate chip lead definition from pcb footprint definition: https://electronics.stackexchange.com/questions/464291/pcb-pads-vs-components-footprints-in-pcb-design

use this footprint string `qfn20_thermalpad`

That's it!
