The object of research is a prototype algorithm that allows to create space trusses by setting only the initial data and controlling the result. Method. Is to develop an algorithm, which creates a space truss by using methods of layout optimization, then optimizes cross-sections of elements and prepares all data for verification calculation and describing characteristics of the design. Then, Using the data from the trial run of the algorithm, compare the results with traditional approaches to the design of spatial trusses. Results. An algorithm for the automated design of a space trusses with an optimal layout has been developed and it has been demonstrated on the example of a specific problem that such an approach will significantly reduce the material intensity of structures. However, all this is possible only with full automation of the design process and considering that all nodal connections are also generated automatically and produced additively using industrial printers.
