UCS
Manages user coordinate systems.
UCSICON
Controls the visibility and placement of the UCS icon.
UCSMAN
Manages defined user coordinate systems.
UCSICON
Displays the UCS icon for the current viewport or layout.
UCSVP
Determines whether the UCS in viewports remains fixed or changes to reflect
the UCS of the current viewport.
Control the User Coordinate System in 3D
Several methods are available for manipulating the user coordinate system in
3D. You can also save and restore user coordinate system orientations.
You define a user coordinate system (UCS) to change the location of the 0,0,0
origin point, the location and rotation of the XY plane, and the orientation
of the XY plane or Z axis. You can locate and orient a UCS anywhere in 3D
space, and you can define, save, and recall as many saved UCS locations as
you require.
If multiple viewports are active, you can assign a different UCS to each
viewport. With the UCSVP system variable turned on, you can lock a UCS to
a viewport, automatically restoring the UCS each time that viewport is made
current.
Define the UCS Location
You can define a UCS in the following ways:
Specify a new origin (one point), new X axis (two points), or new XY plane
(three points).
Align the UCS by selecting a face on a 3D solid object. The selection can
be on a face or on an edge of the solid.
