This study aims to present a classification of methodological procedures for using computer programmes to simulate architectural historical heritage. Produced for a Master’s Degree dissertation in Architecture, the methodology was developed based on several analyses of applications, possibilities and restrictions, with the assistance of photogrammetric reconstruction and several computer-graphics programmes. The files generated enable production of animations recording the changes experienced by buildings at various historical periods. These procedures were applied to the simulation of several buildings around the Praça Dante Alighieri in the centre of Caxias do Sul, Rio Grande do Sul, demonstrating their appropriateness and effectiveness and also showing the potential of computer-simulation resources for the historical environment, both educationally and in appreciation of architectural heritage.
