Soldermask to soldermask might work, but I don't know how to set it, is that
available in Performance option?

Hi all,

I think I do understand the question since I also miss such feature.

Problem stated:
 - to not to have Via too close to SMD pin

Partial Solution:
 - enable same net DRC (problem is that it checks all other rules and often
creates many unwanted DRCs)

Other possibility
 - set a rule for "Solder mask to Solder mask" spacing assuming that Vias
are not covered (problem is that this is one global rule for a whole design)

regards,
Robert
