Scan-to-HBIM for conservation and preservation of Cultural Heritage building: the case study of San Nicola in Montedoro church (Italy)

Abstract

The management of Cultural Heritage (CH) requires increasingly efficient, simple and shareable tools, methods and knowledge. In this environment, a suitable procedure was developed to transform the point cloud, generated by geomatics surveys, into parameterized objects. In order to obtain an object with precise geometric and physical characteristics, a three-dimensional modelling software (Rhinoceros) was used. This software, using the tools and specific plugins, has allowed the parameterization of objects. In particular, the use of the Grasshopper plugin allowed a two-way transformation of the objects between the modelling software and the BIM software (Revit). As a result, any changes to the model made in Rhinoceros were automatically made in Revit and vice versa. The paper shows the potentiality, simplicity and efficiency of the developed method in order to perform the scan-to-HBIM process. This approach was applied to a religious building, located in Italy, belonging to the Cultural Heritage.
