Vertical line (editing of objects) («V»)

If the mode of vertices insert is switched off, at activation of process a piece of a contour, for which current vertex (the vertex which the subsidiary line specifies) is a final one, becomes a vertical piece. That is, position of a vertex after moving depends on a direction of a digitizing.

If the mode of vertices insert is switched on, at activation of process the piece of a contour, which the subsidiary line specifies, becomes a vertical piece. Thus, it is edited (moves) the vertex more close located to a vertex of a contact of a subsidiary line without dependence from a direction of a digitizing.
