The paper describes the final step of a four-year survey of Milan Cathedral. In the past years, several measurement surveys were conducted using innovative techniques such as laser scanning and close range photogrammetry. In particular, the last technique was the most studied, experimented with, and tested because it offers more suitable measurement of a huge complex marble structure. The final aim of the survey was to create a detailed 3D model of the big spire. The last phase of the job, here presented, was to transform the great static model into a 3D WEB BIM for managing and organizing the restoration work.
