**Hi all,** I'm making a PCB to replace my old calculator's circuit, so I could read which button was pressed and use it with an arduino. I used the _"copper area"_ tool to make the connectable key pads. By connectable I mean, the calculator has a squishy layer with pads for each key made of some conductive material between the actual buttons and the PCB, so when a key is pressed, the conductive area gets pressed against the PCB, closing the circuit. Turns out, the _"copper area"_ tool isn't what I was looking for, but I've already _made the shapes and positioned everything_ at the right place. Is there a way to convert the copper area polygons into something, that would work as I intended (expose some copper so the circuit can be closed when a button is pressed)? **My design:**  The key pads in question can be found on the top layer. I hope the design clarifies what I'm trying to achieve, if you need further explanation, please indicate it. **Thanks in advance!**
