Are Named Selections still actively developed?
Named Selections do not survive solid operations. If you compare them with how Breps with per face material or per face display color work, Named Selections seems to be much more fragile.
You can do all sort of booleans on Breps with per face display colors, and colors will stay where they sould stay, you can even split given face into two pieces, and color assigment will still be there.
Contrary, If you will add one face as a Named Selection and do some boolean union on Brep, then even if given face wasn’t affected in any way, you will lose this saved selection…
Brep with some holes. You make a bunch of holes in a brep, and you add them to Named Selections, you make some more holes and you no longer have correctly working Named Selection you previously made.
