17 * \brief Feature for creation of the new arc of circle in PartSet.
18 * The visualization of this object is separated in two parts. The first one is an AIS object
19 * calculated when there is non-initialized attributes of the arc. The second is a result and
20 * it is calculated if all attributes are initialized.
