Actually there are 5 types of apertures circular, rectangular, oblong,

all except the drawn can be used for traces. only the round one will give
you the same width in all directions and gurantee no overshoot from the
traces.

Cadstar specifies an annular ring to draw traces. Apparently the idea was to
prevent overexposure by the overlap of a solid circle.

There is but little in Cadstar that isn't targeted at those who know
little about the electronic design and manufacture processes.
