Resumen
Today, a building is not just a ?body? or a ?machine? as defined by modern architecture, but rather an immaterial entity immersed in a digital world where not only its components but also the information associated with it are accounted for. In recent decades, building information modelling (BIM) has made it possible to move from 2D CAD drawings to 3D models capable of supporting different processes and interacting with different disciplines in the AEC industry for storing, documenting and sharing heterogeneous content. It has thus become possible to direct these techniques towards built heritage to investigate new forms of communication and share heritage building information modelling (HBIM) models. This research investigates this evolution in both generative terms (scan-to-BIM process) and cultural and historical terms in order to orient BIM uses towards novel forms of interactivity and immersion between users and models. The author proposes the use of a digital process and the development of VR and AR environments based on a visual programming language (VPL) to improve access to a deeper knowledge of HBIM models and the artefacts and information contained therein.
