You can update an existing database with Revit model data after changes have been made to the model.
- Subsequent exports to the same database from a Revit model 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 model data to the same database that was originally used with the model; otherwise, unpredictable results may occur.
