Control the Display of the User Coordinate System Icon
The user coordinate system icon (UCS icon) helps you visualize the current
orientation of the UCS. Several versions of this icon are available, and you
can change its size, location, and color.
To indicate the location and orientation of the UCS, the UCS icon is displayed
either at the UCS origin point or in the lower-left corner of the current
viewport.
You can choose a 2D or 3D style of the icon to represent the UCS when
working in 2D environment. Shaded style of icon is displayed to represent
the UCS in the 3D environment.
Use the UCSICON command to choose between displaying the 2D or the 3D
UCS icon. The shaded UCS icon is displayed for a shaded 3D view. To indicate
the origin and orientation of the UCS, you can display the UCS icon at the
UCS origin point using the UCSICON command.
