In-N-Out Family Parameters from Boost Your BIM

1. Select a folder to export parameter data for all families in that folder
2. This produces a CSV file that can be edited in Excel to set parameter values for each type
3. Import this modified file back into Revit to update the parameter values of the families

Use free for a limited number of families during each export, or purchase a license for $9.99.
