Air Bridge Settings
When you are adding a spiral to your circuit, you can also automatically add an airbridge connected to your spiral. The air bridge consists of a via rectangle extending from the interior end of the spiral to rectangular metal polygon extending past the exterior end of the spiral which is connected to a second via rectangle.
None: No air bridge is added with the spiral.
Above: The metal polygon is added on the level above the spiral and the via rectangles extend upwards.
Below: The metal polygon is added on the level below the spiral and the via rectangles extend downwards.
