I have a two terminal component which goes inside the PCB and its two terminals are connected at top and bottom layer of the PCB.
I am facing problem to create the foot print for this. I need to have overlapping pads which connects to different nets. How is it possible?
I created one pin with only top pad and drill. Another one with bottom pad and drill. When I place them at same point to create the complete footprint, it shows DRC (pin to pin spacing violation) error. I dont have any other clue.
Please let me know if anyone have any suggestion.
I'm not sure what your part terminals look like and if the pins are surface mount or through, but here's a couple of possiblities:
If it's a single pin going through the board, you can add the NET_SHORT property to the pin.
If there are two surface mount pins, create two single layer pads (no drill) and if needed add the NET_SHORT property to via(s) that connect the two pads.
Hope this helps.

Thanks Randy. However I am looking for something else. I might not have been clear in last post.
I will make it more clear. The component, let say is a plastic screw with nuts on both side. Both nuts need to connect different nets. That means the footprint is actually a through hole pin only..with pads on both side connected to different nets. So the hole is a non-plated one.
I hope I have explained it now. Please let me know if you have any way to do this footprint.

I have dealt with this before and I believe what you need to do here is build your footprint using the non-plated hole you require and draw circular shapes on the top and bottom etch to represent the pads. Place small surface mount pin inside the shape on top and bottom as the actual pin that the net gets assigned to in the schematic. Once the netlist is read in, the shape will assume the net of the pin in the shape.
