Their dimensions are calculated in the following way, based on the
parameters "Isolate" and "Conduct" along with the drill diameter:
Inner diameter = D + 2 * C
Outer diameter = max(D, Inner dia.) + 2 * I
which: D = drill diameter
C = Conduct (Default: -1000, completely filled)
I = Isolate (Default: 20 [Mil])
With the default settings annulus symbols with an isolation ring of 20
Mils width are generated.
