Shows objects as wireframe with lines facing away from the camera hidden from view
Hidden Line
Selecting Hidden Line is similar to the Wireframe style described above, except that this option only displays the outermost layer of the polygonal meshes facing the camera. Any part of the mesh that is on the far side of the figure, or underneath/behind another object will not be shown to you unless you rotate the camera (or move other items) to view it.
