Summary

The UCS icon displays the orientation of the user coordinate system (UCS) axes and the location of the UCS origin. If the location of the UCS origin is not visible in a viewport, the UCS icon is displayed in the lower-left corner of the viewport instead.

Different coordinate system icons are displayed in paper space and model space. In both cases, a plus sign (+) appears at the base of the icon when it is positioned at the origin of the current UCS. The letter W appears in the Y portion of the icon if the current UCS is the same as the world coordinate system.

A box is formed at the base of the icon if you are viewing the UCS from above (the positive Z direction). The box is missing if you are viewing the UCS from below.

If the UCS is rotated so that the Z axis lies in a plane parallel to the viewing plane—that is, if the XY plane is edge-on to the viewer—the 2D UCS icon is replaced by a broken pencil icon.
