How to set the doors and windows beam？
You are great, thank you
It’s red because it is from a package you don’t have loaded. You need to load that package to get it to work. I’m not sure which package and I can’t check now. Try google the name. I would guess it is either rhythm or ampersand package.
I can not find which package came from. There is no google here
I think it is the ampersand package.
This is a huge loss
