PCB-based touch sensors usually include Vias to connect multiple conductive parts that exist in different layers.
In Sense you can find a via template ("Circular Hole Via"), that is is a vertical cylindrical conductor with a padding:

side view:
Both radii are given in mm, whereas thickness is ignored at the moment and surface conductors are used.
In case that your Layout includes Vias, you must also set up their height and vertical position in the corresponding tab in StackUp.
