A computer-implemented method for manipulating three-dimensional modeled objects of an assembly in a three-dimensional scene comprising the steps of: displaying a three-dimensional bounding box (BB) encompassing at least one three-dimensional object, a face of the surface of the bounding box (BB) comprising a plurality of interactive surfaces which are parts of the face; hovering pointing means (PM) on the bounding box (BB); and if at least one face of the surface of the bounding box (BB) is displayed such that its interactive surfaces are not accessible for the pointing means (PM), displaying a wider surface (WS) that allows accessibility of said interactive surfaces.
