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.
You can also hide the UCS icon based on the current visual style, and whether
perspective is turned on. Three system variables are available:
Use UCS2DDISPLAYSETTING to hide the UCS icon when the current visual
style is 2D Wireframe.
Use UCS3DPARADISPLAYSETTING to hide the UCS icon when perspective
(PERSPECTIVE) is turned off in a viewport with a 3D visual style.
Use UCS3DPERPDISPLAYSETTING to hide the UCS icon when perspective
is turned on in a viewport with a 3D visual style.
NOTE These system variables take precedence over the UCSICON setting in
viewports with certain visual styles.
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.
