Ducts beyond showing as crosses

[pleasantc]

I have a building section looking at a wall. There are ducts, well beyond said wall, that are showing through the wall as little (blue, pink & green) crosses. I need the ducts that are visible in the room I'm cutting through to show, so I can't turn ducts off. And there are about 20 of them, so I don't really want to select them individually to hide them. Thoughts, anyone?

Thanks!

Ha! Never mind! I turned off Duct Center Lines, and they're gone! :)
