Métodos de documentación, análisis y conservación de trazados arquitectónicos a tamaño natural

Full-size tracings have played an important role in architectural history; they do not pose the scale change problems involved with drawings in paper, allowing a precise execution of any architectural member. As a result, they furnish valuable data about the constructive history of these members, provided that a precise survey, both of the tracing and the architectural member, is available in order to compare both and measure the precision of the execution. This paper explains the methods used by the authors in the documentation of a number of tracings in Early Modern Spanish buildings, including also the survey of the architectural members they depict, ending with the challenges posed by the conservation of these key material sources of architectural and construction history.
