Display and Hide the UCS Icon
In some circumstances, you might need to hide the UCS icon. With the
UCSICON command, you can turn off the UCS icon in a single viewport or
all viewports. Each layout also provides a UCS icon in paper space.
Variations in UCS Icon Types
The UCS icon is displayed in various ways to help you visualize the orientation
of the work plane. The following figure shows some of the possible icon
displays.
You can use the UCSICON command to switch between the 2D UCS icon and
the 3D UCS icon. You can also use the command to change the size, color,
and icon line width of the 3D UCS icon.
The UCS broken pencil icon replaces the 2D UCS icon when the viewing
direction is in a plane parallel to the UCS XY plane. The broken pencil icon
indicates that the edge of the XY plane is almost perpendicular to your viewing
direction. This icon warns you not to use your pointing device to specify
coordinates.
When you use the pointing device to locate a point, it's normally placed on
the XY plane. If the UCS is rotated so that the Z axis lies in a plane parallel to
the viewing planethat is, if the XY plane is edge-on to the viewerit may
be difficult to visualize where the point will be located. In this case, the point
will be located on a plane parallel to your viewing plane that also contains
the UCS origin point. For example, if the viewing direction is along the X axis,
coordinates specified with a pointing device will be located on the YZ plane,
which contains the UCS origin point.
