Nice! I was considering a mod like this with “B” as the align point, but forgot about it. I think I got sidetracked experimenting with another “face align” idea that never went anywhere.
And it’s implemented as a modal to!
The modded version 1D_Inc linked to is based off the 2017_09_29 version of NP Station for 2.78 / 2.79. It won’t run on 2.80.
You have an updated version of NP Station on github?! I wish I had known earlier, I would have merged those changes in to the “official” version in addons-contrib. That is where I have pushed all my NP Station updates to.
I agree, especially with the snap improvements Mano is working on that could require API changes.
I did do some experimenting with a 2.80 version of NP Station that would be based around the code changes I made for my Three Point Arch tool (with some of the API updates in the addons-contrib version of NP Station), but the code is not very far along.
