Summary
The UCS icon indicates the location and orientation of the current UCS. You
can manipulate the UCS icon using grips. This is controlled by the
UCSSELECTMODE on page 1704 system variable.
NOTE 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 model space, you can choose between 2D and 3D icon display styles
(see the Properties on page 1273 option):
■ 2D. The letter W appears in the Y portion of the icon if the UCS is the same
as the WCS (world coordinate system). 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.
■ 3D. A square is displayed in the XY plane at the origin if the current UCS
is the same as the WCS, and you are viewing the UCS from above (the
positive Z direction). The square is missing if you are viewing the UCS
from below. The Z axis is solid when viewed from above the XY plane and
dashed when viewed from below the XY plane.
