I've checked settings in as many places as I can think, but I can't drop any vias.
Can't figure out why all of a sudden I can't drop a via.
Anybody have any ideas on the most likely places & not so most liekly places to look.
It doe shave blind vias 1-6 & 7-12 along with a couple thruu sizes.
Thaey are all in the list as usable. Drill pairs are set up.
Can't see where it went south
