The method of parametric modeling and design based on the example of a building is studied, the architectural image of which is a set of circular helical and cylindrical surfaces defined by coordinates through functions of the corresponding surfaces in the SAPPHIRE software. Alternative methods for specifying surfaces in the SAPPHIRE PC, AutoCAD with subsequent export to the LIRA PC for engineering calculations of the frame of the building for various combinations of loads by the finite element method are presented. The object of the study is a 360-meter-high building with a hardness core in the form of a cylindrical shell of revolution. The height of the floor is 3 m. Around the rigid shell there are three circular helical surfaces that "rise" in a spiral upward along with the core of rigidity to a mark of 360 meters from the level of the ground floor. One of the most universal ways to create a surface is to specify it through a formula, because you can easily change the shape and appearance of the surface without manually editing the geometry of the model in the drawing. The development of the parametric architecture calls for the creation of new approaches to the calculation of unique buildings and structures, the improvement of software complexes that implement the finite element method, and the appearance of new varieties of finite elements with curvilinear boundaries.
