« Drawing is not an exact representaion of the work.  It is not definitive.  The artrist retains an element of freedom and chance in the creation, although there is no improvisation.  Dietrich-Mohr forces the material towards his idea, but the material does not always give way.  One does not model metal as one does earth and sometimes it does not easily submit to the lines of the preparatory drawing.  So the artist takes up his paper and pencil to get around the sometimes unturnable nature of the metal. »
