Visual Programming Language to Support Interoperability of Geometric and Data Modelling in HBIM Processes

HBIM is widely used as a management system to support documentation, conservation and enhancement of historical buildings. However, multidisciplinary activities often require the integration of different software environments to support tailored geometric alphanumeric data representation and to keep all experts within their digital tools of choice, but interoperability is still challenging. This study proposed a digital workflow, based on a Visual Programming script, to seamlessly integrate the use of CAD programs for modelling complex shapes and the use of spreadsheets for data manipulation with BIM tools, within a unified information management system, applied to historical buildings and floor constructions. It confirms the complementarity of different data modelling methods and demonstrates the effectiveness of Visual Programming in supporting the digitisation and management of built heritage.
