This document provides instructions for creating a photo-realistic 3D model of an existing building using various software programs. It involves taking measurements of the building from Google Earth and Bing Maps to create a massing model in Sketchup. Materials are created using photos of the building skin taken from Bing Maps and applied to the model. Floors and a structural cage are modeled, glass is added and recessed, and a sign is created. The process aims to illustrate how to create an accurate, detailed 3D model of a building based on site measurements and photos.
