Running DRC always reports all microvias as drill size errors regardless of
the settings in the DRC sizes tab for microvia drill and ratio. The net
class drill sizes are set to 0mil.
The only way I have found to influence this is to reduce the 'normal' drill
size value to that of the microvia drill size.
Is this a feature?

Also, the thickness of the microvia layer is used to verify the ratio I
guess..
I got isolation set to 0.2184mm for upper and lower layers.
Maan, this is too early for my brain
The correct isolation is 0.066mm
for the pcb using microvia.
My layer stack is defined as:-
((12)3*4(516))
The eagle graphic shows the two type of via. One going through all layers
and two going through the outer to the next inner.
I have 0.1mm isolation on the two outer layers and 35um copper.
