I've been struggling with Altium and can't find a rule-set that seems to let me do what I want: I want the plane-swell (clearance) around thru-board signal vias to be 9 mil on GND layer but 14 mil on PWR plane layers. This was easy to do in PCAD but seems impossible in Altium. Any ideas?
I've tried various prioritized rule permutations using IsVia(), ExistsOnLayer(), etc. But the via exists on multiple layers. And the rules seem to only care about the object penetrating the layer, not which layer the plane itself is on.
About to give up and just set the IsVia() clearance on planes to 9 mil and draw 14 [+via diameter] mil circles around each and every via on the non-GND layer
And a custom via stackup with bigger annular ring doesn't help, because it doesn't change the distance from the outer extent of the via metal to the plane metal, even if it makes the circle larger.
