Hello, I am creating a scheme with curtain wall. In design layer view the entire scheme looks how it should. When I go to my site plan the curtain wall doesn't show up. I have checked the correct layers/classes etc are turned on. I have also put a standard door in the curtain wall which does show up in site plan on its own, just with no curtain wall around it. I'm sure it's something incredibly simple, but I cant seem to figure it out. Help greatly appreciated.
