Two-stage modeling of a parametric architecture object of a complex parametric architecture are considered in the article. At the first stage it was analyzed the evolution of the formation of an analytical surface obtained by rotating the Lame curve in a plane perpendicular to the axis of rotation. During the investigation were considered changes in the intensity of rounding of the corners of the shape in the horizontal plane. Study of screw parametric surfaces was carried out at the second stage. New forms of a superellipse were developed to solve the problem of determining the surface of an object of parametric architecture that is resistant to aerodynamic impact. Numerical experiment with use of the finite element method in the ANSYS PC allowed to construct a new analytical surface with a different angle of twisting of floor slabs along the height of a unique building. The proposed method of research and application of the possibilities of the evolution of shaping allows to proceed to the modernization of BIM technologies in the design of unique buildings and structures.
