Parameterization has shown potential in creating architectural projects and verification steps. The objective is to develop a parametric and generative tool, containing the urban parameters of the Master Plan of a municipality, to assist in the phase of field study. The model is developed with the aid of Revit software and Dynamo plug-in. The results converge to a tool where users enter the lot's dimensions and zoning, and it applies the other parameters. It is possible to analyze the constructive potential quickly, avoiding errors. The parameterization process is emphasized, encouraging the user to apply new methodologies in early project stages.
