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

I seem to remember that you might have trouble manually inserting a via if there is more than one via type defined. Start a dummy route, right click and select the via type you want. You should be able to insert it now.
Thank you to both posters for help!
I really feel silly now, totally forgot that anytime drill pairs are set up with a partial pair you MUST also set up a Top & Bottom pair.
I looked at that menu a number of times and it just didn't click.
I finally spotted the error message that pops up quickly when placign a via which led me to pair set up menu one more time
which is when that huge light bulb went off in my head.
Do you have any net or conditional or other rules set?
You may have to allow the vias under those settings also.
