The user is asked over the command window to identify two or more existing points. The issue of the distance occurs in metres in the command window. In the graphics a Rubberband which lists on top the distance to the previous point, below the total length of the given line segments is carried along. The number of the postcomma places amounts to maximum 3. On finishing a segment the single length and sum length is placed in the middle of that. The issues are removed with the new drawing.
