Import Project Parameters command set has the following two sub commands:
Import to Open Projects
Import to Project Files
Import to Open Projects is to import some chosen project parameters from an external PP.txt or PO.csv as Project Parameters into the chosen projects that are opened in Revit. If no projects are open in the current Revit session, the command will not be available.
Firstly a PO.txt or PO.csv needs to be picked.
Secondly, some project parameters need to be chosen.
The Import to Where button around the top-right corner is to specify which project models to import the project parameters into.
It can be also confirmed after the OK button being pressed.
All of these can be exercised in the trail edition of Revit Parameter Organizer.
