Hi!
I’m working on a project that has a monospaced axis. At the moment these are two separate files. I’d like to have all these masters as one file, but what’s stopping me are metrics keys: the proportional masters have lots of metrics keys while mono of course don’t have any. I can’t think of any simple way to merge the two except adding == to all mono glyphs but that would seem very annoying to work with.
Am I missing a potential solution, or should I just stick to different font files until production?
Merci!
I would stick the metric keys at the layers (adding ==). A script can do that. A script that keeps them in sync would be handy, too 
Still running into this… So I’ve been thinking what would be the perfect solution would be to create some sort of metrics keys groups. Maybe a master CP “link metrics keys to master” could work?
“==” works well but only for small exceptions, otherwise it becomes very slow to use unless scripted. So this could be a really nice addition?
I don’t see how that CP would help?
So that metrics keys would apply only to certain masters?
I had a similar idea but for italic reasons: CP defining something like “this master is group B of metric keys and kerning groups” and in UI the metric keys/kern groups would be totally independent when you switch to masters of group B. Have metric key n in some masters, g in some others and empty in the rest if you will. Never bothered to suggest because sounds like a lot of work and you can work in two files or add ==.
