I know this topic has been discussed many times before, but I have tried a number of things learned from previous posts to no avail. I have a SIP wall with a SIP attic wall above and for some reason it is displaying a line between the two on my elevations. As you scroll in and out, it will disappear and reappear. I cannot for the life of me figure out how to fix it! I am sure it is porbably something to do with not having the right combination of settings or something... Please help!
