Hello, I've been having ongoing issues with coloured elevations once it has been sent to layout. I always get these white dashes throughout the elevation image and I have no idea how to fix this problem. I've attached an image. This is my settings when I send to layout: Send Options: Entire Plan/View Camera View Options: Plot Lines, (Colour Fill, Edge Line Defaults, Pattern Line Defaults all checked) Scaling: 1/2" = 1'-0"
