The steps of constructions are the following:

(i) Given \bar{PQ} whose length is not known.

(ii) Fix the compasses pointer on P and the pencil end on Q. The opening of the instrument now gives the length of \bar{PQ}.

(iii) Draw any line 'l'. Choose a point A on 'l'. Without changing the compasses setting, place the pointer on A.

Draw an arc that cuts  at 'l' a point, say B. Now \bar{AB} is a copy of \bar{PQ} .
