Ghosting of lines below a surface
-
In my SketchUp architectural model, I have a series of trusses (each one is a group entity) below a single roof surface which is 1/2 " above the truss entity. My issue is the ghosting of these trusses through the roof surface. When zoomed out one can clearly see the lines for the top chords of the truss. This happens in all views as I orbit the model. As I zoom in they disappear.
I tried offsetting the surface more but they still show (ghost) through. I am in shaded texture style.
Thoughts? I appreciate the help. Apologies for any miscues - this is my first post.

That's not unusual because at the viewing distance required to see the whole roof, the distance between the roof surface and the truss is practically nothing. The graphics card and OpenGL have tolerances and your exceeeding them. The fix is to assign a layer to the truss components and turn that layer off when you are looking at the overall roof. Turn on the truss layer only when you need to see the trusses.
If you've drawn the framing in the walls you might consider doing the same thing. Remember that you don't need those trusses to keep the roof up in SketchUp. Turn off layers for things that can't be seen. Not only do you prevent the issue you're describing but you also may improve performance when moving through the model space.

There's a bit more info on this here.

Thanks.
I went ahead and hid the top 'offending' surface of the trusses and this seems to work as suggested in the linked info. I like the idea of creating a layer and then turning it off and on in the scenes as needed.All good and thanks again for the help.
