Flat plane appearing above existing geometry

Yes the lines are showing through because they occupy the same space as your plane. You can give your plane thickness or hide the lines of the trusses to avoid this. See below.

Lines from behind showing after zooming out

Hello Sketchup users, I have a problem in my drawing. When i zoom out, the lines from hide objects are showing but after zooming in all lines are gone. I want to remove that lines because i’m trying to print screen on my drawing and make a jpg file of it. I don’t use export as jpg cause the line are very thin when exported.TIA See attached image below.
