Batch update Revit parameters
Workflow
The workflow closely resembles the operation of the Diroot Sheetlink Add-in:
Export parameter data (one or multiple parameters) to a CSV file (an empty CSV file must be created in advance).
Update the parameter values in the CSV file.
Import the updated CSV file back into Revit to refresh the parameter values.
Limitations
This process supports the updating of text parameters only.
It cannot update parameters for elements within groups.
