With this function, an existing displacement line can be deselected or a new displacement line can be selected . If the function is active, the points / lines for which a displacement line can be selected or deselected are marked. The cursor symbol indicates whether a displacement line already exists or not . Any line of the active part can be selected as displacement line. The right principle must be considered, as this determines the move direction.

The function cutting line is only active for the type circle with direction . Having selected the cutting line, the new circle does not have a given radius; the radius is a result of the cutting line. Clicking on switches to the mode for selection of the cutting line. A set cutting line can be deselected in this mode.

An interactive circle of the type circle from point to point or circle with direction can be switched to the other type at any time after calling. Clicking on one of the two buttons in the context bar starts the click process where either the periphery point ( switch type: point to point ) or the direction ( switch type: with direction ) must be re-defined. The original central point is always transferred during type switch.

With click new, the entire click process is gone through again. The basic elements of the active function, e.g. points, lines, directions are queried one after another. You can decide separately for each basic element whether to retain it or set it again. A right click accepts the original position/ setting.

In this way, individual points for the circle can be retained with a right click and other points can be re-defined.
