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 line with direction . Having selected the cutting line, the new line does not have a given length; it is extended to or cut off at 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.

The original starting point is always transferred during type switch.

You can decide separately for each basic element whether to retain it or set it again. A right click accepts the original position/ setting.
