Kotelys measures directly on your PDF or scanned drawings: lengths, areas, counts, heights, thicknesses, deductions for openings and voids. Each item becomes a type with its own colour and total; zones split quantities by flat, floor or phase. Reports are ready to send: summary, detailed take-off report with every calculation written out, annotated drawing set and Excel workbook. On the same drawing, Kotelys also draws the site layout plan: tower cranes, site cabins, fencing, plant, signage and legend. Designed in France for French practice.
