See my problem:
For a certain net-classes, on external layers, I have to respect a clearance of 6mm.
But in inner layers (in the prepreg) I can down the clearance to 1mm.
If I route manualy in inner layer, I can ignore the external clearance and accept the DRC errors.
But the polygons in inner layers respect the 6mm, that is my problem!
I suggest either:
two Clearance Matrix
One for External layers
One for Internal layers
or more simply a global Reduction Factor for Clearance in inner layers by a percentage with a
minimum limit.
