Bring To Front

This option is relevant for better viewing of complex 3D models. It allows to bring to the viewer foreground the selected geometrical object.

Let's take for example two coincident primitives: a box and a cylinder.

In the first picture the box has been visually superimposed over the cylinder using Bring to front option.

In the second picture the box has been returned to its normal state using Clear Top Level State context menu command, however, the cylinder has been brought to front.
