The article presents the results of theoretical and experimental developments regarding the marking of scans and patterns of fittings of the ventilation system, provided that the unification of installation and procurement work. The aim of the work is to create a graph-analytical method to unify the construction of patterns of ventilation fittings, in particular in the design and manufacture of adapters of different shapes and sizes; increasing the efficiency of procurement work for the installation of ventilation systems in production facilities by minimizing material waste during their manufacture, and reducing the material consumption of products. The application of the proposed graphic-analytical method will increase the efficiency of procurement and installation work and thus reduce the amount of waste and material consumption for the manufacture of ventilation fittings for various purposes.
