Pairs of sheets, some called originals (1). They are transparent and have different sizes with references (2, 3) at several levels. To arrange on the models to reproduce. The others called reproduction sheets have different sizes or fractions but with similar references to the original ones. These could be used under the paper by transparence, or on the paper so as to reproduce the references through the perforations.
