Mesh shows through?

http://i52.tinypic.com/vffhmt.png

In the picture above, which is a snapshot of my problem, i have the highlight crate in blue, the whole problem area in red, and the wall outlined in green. These creates are actually behind the wall, but when I am modeling, they appear to be in front of it. When I render a picture out its fine, but when modeling it is very difficult. Any help would be much appreciated.

maybe you have setup those cubes (->objcect->display) as “x-ray”
which makes those object to be drawn in front of all others …
… a way to mark them but if you would mark a lot objects in this way
… you may get confused about there positions.

Normaly it is used for armatures, to make the armature visible thrugh the mesh.

Thats what it was, thanks man :slight_smile:
