7.2.130 ui-center-origin

(ui-center-origin [origin|bbox-center])

Set the origin of the coordinate system of the CENTER objeto for user interface (i.e. mouse) controlled movimentos. The keyword origin means to use the origin of the coordinate system of the currently selected objeto, while bbox-center means to use the center of the bouding box of the current objeto. The keyword bbox-center makes no sense if the geometry is non-Euclidean. Using either bbox-center or origin does not make a difference if the objeto do centro is not a geometry, e.g. if it is a camera. Same holds if the World is the currently selected objeto.
