Complex Spaces in HBIM Models: Volumetric Visualization for a Data Insertion

[ES] In recent years, digital technologies are increasingly being used to document and monitor heritage buildings, acting as decision support tools for technicians and managers working in these buildings. Among the most widely used tools, HBIM (Heritage Building Information Modeling) as a methodology for virtual documentation of information on heritage buildings and their life cycle, and sensors as tools for recording environmental data of extreme relevance for preventive conservation, maintenance and visitor management in heritage buildings stand out. This paper presents a 3D modelling process using BIM software, where the model allows a more accurate measurement of the volume of interior spaces in rooms bounded by complex ceilings. This process also makes it possible to visualise the spatial volume in 3D as well as to attribute informative parameters to it. For this purpose, the vaults of the church of the Real Colegio-Seminario del Patriarca in Valencia, Spain, have been used as a case study.
