You can use the Remove command to remove a conductor from its parent. To access the command, right-click the mouse button on a conductor and on the shortcut menu, click Remove.
When you remove a conductor from a higher level object, it is removed from the definition of all higher level objects. The existing to and from points of the conductor are maintained. The path segment(s) shared between the selected conductor and its higher level is removed from the conductor's definition. A new segment is generated to replace the segment that was removed.
