Notice that a cube is displayed in the upper right-hand corner. This is
the AutoCAD ViewCube, which provides visual feedback of the current
orientation of a model. You can use the ViewCube to adjust the viewpoint
of the model when a visual style has been applied.

with dragging the ViewCube to various positions. When you are finished,
click to return the model and ViewCube to their original positions.

The effect is not realistic, but it can make the details of the model easy
to see.
