BIM Reverse Modelling Process for the Documentation of Villa Rufolo in Ravello

Abstract

The primary purpose of this work is the definition of a protocol for the accuracy check in a BIM process, from digital survey to three-dimensional reconstruction. The development of a BIM model for existing buildings is, in fact, basically a reverse engineering operation and, as far as the reproduction of the geometries is concerned, a coded pipeline for the accuracy control is still missing. The result of the modelling process is a local volumetric entity where the object of interest is decomposed into portions and each element is described through a finite number of parameters. This model then becomes the repository of all the systematised data collected for Villa Rufolo, a landmark of the Amalfi Coast, to define an environment that can offer a valid support to decision-making processes for future restorations.DOI: https://doi.org/10.20365/disegnarecon.26.2021.1
