Architectural 3D modeling in historical buildings knowledge and restoration processes

The validation processes of restoration projects in all institutions are still based on communication and training requisites which continue to influence choices during the preparation of projects, and not only in purely formal terms, but also with respect to content. These requisites are paper documents and digital media, i.e. reproductions of paper documents in PDF format. Furthermore, project representation and communication are substantially established in two-dimensional form (plans, elevations, sections) with rare inroads into three-dimensional formats for explicative and integrative purposes (axonometric and/or perspective images), with the usual separateness, which is also logical and conceptual, between graphic representation and documentation, during the surveying and analysis phase and during the design phase. Even considering recent experiences related to the management of the reconstruction phase in the historical centres affected by the earthquake in L'Aquila on 6 April 2009, the intrinsic possibilities of using of architectural 3D modelling is to be examined, with the purpose of building an information system dedicated to architectural specificities, and to building the project proposal, fully directing its communicative complexity to the synthetic and interactive support of 3D modelling.
