Autodesk's model-review and coordination tool for federated BIM models. Autodesk's dedicated tool for reviewing large, federated BIM models from multiple disciplines and multiple software packages at once. Navisworks aggregates models (Revit, IFC, DWG, and more) into a single lightweight federated view, runs clash detection, drives 4D construction sequencing, and manages coordination issues, often exchanged as BCF files with the design team.
It is not a modeling tool - nothing gets designed in Navisworks - it is where coordination and construction planning happen once the discipline models exist. On many contractor-led projects, Navisworks (or a competitor like Solibri) is where the "real" coordination meeting actually happens.
