You can update an existing database with Revit project data after changes have been made to the project.
- Subsequent exports to the same database from a Revit project overwrite the same data stored in the database table; however, any new fields or tables remain intact and unchanged.
- Each table's ID field is used to locate the same records for update when exporting to the same database. This allows any new fields to remain intact and the data to remain linked to the same record (via ID) even after subsequent exports.
DANGER: Only export project data to the same database that was originally used with the project; otherwise, unpredictable results may occur.
