Modeling of complex geometry small architectural forms using visual (parametric) programming

Project implementation necessitates working with models of small architectural forms. Their geometry becomes more and more complex every year in accordance with modern requirements. Many small architectural forms contain repeating elements that change according to complex laws and are located along curvilinear trajectories. Such objects are a challenge even for experienced designers. The parameters of these objects must be changed when integrating them into the architectural environment. These changes must also appear in the model instantaneously. When modeling and adjusting the parameters of objects, it is necessary to satisfy certain requirements of the model both at the beginning of the design stage and at subsequent project stages. The presented article is devoted to solutions for these problems. A proposed solution is demonstrated for specific objects of the architectural environment required for the development of projects: a canopy and bench; a bench made of polygonal elements arranged in a circle; a summer pavilion; and a decorative wall. The obtained models of small architectural forms and the scripts developed for them (executed in Grasshopper and Dynamo) are presented. The resulting models are successfully imported into graphic software, including BIM programs (Archicad, Renga, Revit and others).
