DIGITAL INFORMATION MODELING AND KNOWLEDGE

The article investigates the architectural drawing central role within heritage buildings knowledge. The fact is validated in both traditional tridimensional modeling procedures and advanced features. A simultaneous and collaborative analysis researches about the Eremitani’s church in Padua, demonstrate that representation is, in the early steps, an analytical knowledge container of historic documents, geometric and material surveys, historical constructive techniques. Later it represents a tool to create a public, shared, multi-layered knowledge. Moreover, architectural representation is, as itself, a well-known procedure to gain understanding, forcing users to examine geometrical and constructive relations of any object. The development of building information modeling allows to link modeled objects and various information. The procedure creates the information drawing-paradigm and new architectural drawing extensions and possibilities. Architectural drawing becomes a validation and codification reviewer of tridimensional survey and documentation research. Since the representation has to be internally consistent, information has to be coordinated and compatible among the space and building phases. Therefore, users could represent any incompatibility graphically and textually. In this sense, drawing can originate new avenues in the way cultural heritage is studied by researchers, as a multidisciplinary analysis tool. At the same time, it changes the system that common users approach to heritage buildings in tourism marketing strategies. The use of mobile applications and augmented reality - which extend the user’s exhibition experience - and constructive components from tridimensional printing, increases architectural drawing meaning and implementations’ possibilities.
