A straight spool drawing gives centre-to-centre distances A=800, B=1200, C=600 mm for three separate pieces. Each piece has one fitting at each end; the supplied axis-to-cut takeouts are 75 mm and 65 mm. There are 3 identical sets. These takeouts already include all allowances; do not add a welding gap or infer a fitting standard.
Calculate the cut length A in mm. Keep intermediate values unrounded; round the final result to four decimal places if necessary.
