The UCS Icon
The drawing area displays an icon representing the XY axis of a rectangular
coordinate system called the User Coordinate System, or UCS.
You can move or rotate the UCS icon with the UCS command, or by clicking
and dragging the icon using the grips that are displayed. The UCS is useful
because it controls features that include
The angular orientation that defines horizontal and vertical
The alignment and angle of the grid, and hatch patterns
The origin and orientation for 2D and 3D coordinate entry
You can change the appearance of the UCS icon with the UCSICON command,
Properties option. With this command, you can also control whether the UCS
icon is visible.
