The Progettazione Tecnologica Assistita course was based on learning the functionality of the Archicad (Bim) software applied to a real context. The stable inside the monumental complex of the Certosa di Pavia was taken as a case study. The architectural survey was carried out on the stables, which was used to create the three-dimensional model through Archicad. From this model, plans, sections and elevations were extrapolated and the photo-straightened facades were subsequently superimposed. This model was also of fundamental importance already during the modeling itself to draw conclusions on various technical structural and constructive aspects. Furthermore, some of the facades of the stable were extrapolated from the photographic survey through the use of Metashape
