This study aims to examine the current status of parametric design in architecture, which is gradually spreading owing to the increasing use of computers, and to understand the trends in the use of parametric design software. The GrasshopperⓇ definition files, which are used in architectural parametric design, were collected on the internet. Subsequently, the frequency of appearance of each component was computed using a parsing process. For the analysis of tendency in component use, GrasshopperⓇ components were classified into four types: value, action, generation, and extraction, in terms of form generation. Furthermore, analysis of appearance frequency by type found that parametric modeling relies largely on intuitive and simple object manipulation methods similar to general 3D modeling. From the parsing results, the combination pattern of components was analyzed through cross-frequency analysis between each component, and several representative combination patterns were derived. The combination of each component tended to be used more frequently than arbitrarily. In this study, we successfully examined the current state of parametric design in architecture by microscopically approaching the use of GrasshopperⓇ setting the stage for a theoretical study of parametric design.
