It's a feature that check only solder mask between pins and vias . It
is located in constraint manager in "Design constraints" field. But it dos not check entities manually added on package_geometry/soldermask and the property nodrc_sym_same_pin is not usable with. Not a great feature according to me, it have to be improved...

What is the function of the soldermask alignment drc?

I can't believe I have never seen that one in there. Using "sm to sm" works for via to smd. Also a pleasant surprise, this does not give me drc's where I allow a soldermask shape to cover over pads that already have soldermasks. I'm guessing this rule will show up with occasional bogus drc's, but nowhere near as bad as if I pushed the same net button.

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 Macindoe, Gary wrote:Hey Pat, Not exactly sure what you are asking here.

The one I always need is via to smd pin, but I would not want all the rest of the rules to have same net application.
