Method

Specify a new UCS origin through one, two or three points in the drawing or choose one of the command’s options.

Options within the command

Face
Aligns the UCS to a face of a 3D solid.
Note: This option works only with flat 3D faces and not curved ones, such as on a sphere.
Flip
Reverses the direction of the Z-axis.
Xrotate
Rotates the UCS 180 ̊ about the X-axis.
Yrotate
Rotates the UCS 180 ̊ about the Y-axis.
NAmed
Creates, restores and deletes UCS names.
Restore
Allows you to enter a UCS name to restore.
Save
Allows you to enter a name for saving the UCS.
Delete
Allows you to enter the UCS name to delete.
?
Lists the names of UCSs in the drawing.
Note: Type:
  • *to list all UCS names.
  • name* to list name of UCSs that begin with name.
  • name to list the UCS specified by name.
Entity
Aligns the UCS to a selected entity.
Select entity for UCS definition
Represents the orientation and type of entity defining the orientation of the UCS.
Note: The UCS origin is located to the end point, center point, or vertex closest to the pick point. The X-axis is aligned with the entity or an edge. The X,Y-plane is aligned to the entity's plane. For ambiguous objects with obvious orientation, like a circle, the orientation is maintained.
POintcloud
Defines the UCS based on the normal of a point selected in a point cloud.
Note: Make sure that in the 3d entity snap mode category of the Settings dialog box the Turn off all 3D snaps option is disabled and the Point cloud nearest point option is enabled (see the 3DOSMODE system variable article).
Select point for UCS definition
Defines the origin and gets the Z direction from the point cloud normal. Accept or continue to define the X-axis.
Point on X-axis
Allows you to select a point in the point cloud to define the X-axis. Accept or continue to define the Y-axis.
Point on the XY-plane with positive Y value
Allows you to select a point in the point cloud to define the XY-plane.
Note: The Flip, Xrotate, and Yrotate options become available after accepting any of the options above.
Previous
Changes the UCS to the previous one.
View
Sets the UCS to the current viewpoint.
Note: The x axis and y axis are parallel to the view edges. The z axis is perpendicular to the view, with positive Z-axis pointing to the viewer. The origin is copied from the previous coordinate system.
X
Rotates the current UCS about the X-axis.
Y
Rotates the current UCS about the Y-axis.
Z
Rotates the current UCS about the Z-axis.
Z Axis
Sets the UCS relative to the Z-axis.
Note: Y-plane is perpendicular to the Z-axis with the X-axis horizontal and the Y-axis pointing upwards.
Move
Moves the origin of the current UCS, keeping the orientation of the axes.
World
Switches to the world coordinate system (WCS).
