Dalla geometria delle preesistenze alla conoscenza della costruzione: un’esperienza di recupero aggiornata dalla metodologia BIMFrom the geometry of pre-existing to the construction knowledge: an updated recovery from BIM

Lexically, the verb to construct means to reorder the individual parts of the operation following grammatical and logical connections, linking and arranging them according to the rules and the use of language. Similarly, today's BIM have the capability to develop projects by following the rules of good constructor, and a precise control of geometry and of the different representations types. It will be also analyzed the renewed relationship between Survey and Design, in a particularly fertile background in which Geometry is investigated in its versatile properties and Drawing plays a role of greater visibility and effective relevance.
