Abstract: Focused on the conservation of cultural relics in Yuncao, this study departs from traditional preservation approaches and proposes a paradigm shift by leveraging Building Information Modeling (BIM) technology. The methodology involves information collection, three-dimensional reconstruction, and lifecycle management of the ancient buildings in Yuncao, ultimately achieving a comprehensive digitized preservation. This innovative digital approach not only presents a feasible systematic solution for the conservation and inheritance of cultural heritage in Yuncao Ancient Town but also introduces new directions and perspectives for the protection of ancient buildings in Anhui.
