Lines bleed through plane in 3D view

[2017839411]

Hi! I'm having a problem where lines behind a plane bleed through if I'm on 3D. This shows even in exports. I think it happens in small scale drawings. This also happens even if the geometry is made in one whole extrusion.

Here are some examples, as you can see, on one image, the casework is made of one extrusion, but the shelf still bleeds through the side panel. On the other image, the sheet is placed on top of the beams, the sheet is 16mm, but as you can see, the beams still bleed through it. Anyone knows what's causing this?

that's happen usually when the Faces of two elements overlap (are in the same Plane) 

So, either use a slight offset from the surface (for the second element) or try to Attach one element to the other one ( as in case of Floor Surfaces ....Wall attached to Floors)

It's a known and documented issue.
