Why Worksharing Exists: The Problem With Single-User BIM Files
A Revit project file is not a simple text document that two people can edit simultaneously in a shared folder. Revit's parametric engine — the system that keeps walls constrained to levels, propagates dimension changes, and updates all views in real time — requires exclusive access to write to the model database. If two users opened the same .RVT file from a network drive simultaneously and both saved their work, the second save would silently overwrite the first user's changes. On a project with a 10-person BIM team, this approach is unworkable.
