This paper focuses on the creation of a new Grasshopper’s plugin within the Rhino software, specifically aimed at facilitating the modeling of diverse brickwork shells with complex designs, particularly focusing on brick arches. The plugin, dubbed PoliBrick, distinguishes itself by simplifying parametric modeling across a wide array of free-form shells, which proves invaluable for crafting intricate brick arch patterns. Its operational approach stands out from existing methods by enabling parametric modeling across all free-form shells. With a keen emphasis on user accessibility, PoliBrick is designed to feature a user-friendly interface, equipped with just six essential tools to streamline the modeling process. The primary objective of this endeavor is to establish a real-time, feedback-driven design revision method, empowering users to effortlessly generate various brick patterns, including basket weave, stretcher bond, herringbone, and more, while also seamlessly integrating post-analysis for the structural investigation of curved structures by integrating the tool into software of varying complexity, employing preferred methodologies such as finite or distinct elements. Through PoliBrick, a novel approach emerges, revolutionizing the way brick patterns are conceptualized and implemented within architectural design workflows. The procedure is validated through benchmarking against various types of ancient vaults and dome patterns selected by the authors for which the robustness of the proposed algorithm is confirmed.
