This seminar proceedings titled Il disegno: dallo schizzo al computer (1993) digestively examines the evolution of architectural drawing from free‑hand sketching to digital computer‑aided techniques. Organised by the Department of Configuration and Implementation of Architecture at the University of Naples “Federico II”, the work investigates how drawing practices, representational conventions and graphic media shift when transitioning from manual to computer systems. It emphasises methodological implications for the representation of form, spatial thinking and project development in architecture and engineering, bridging traditional techniques with emerging digital workflows.
