Creating a blank text parameter for all elements

Hi all,

I’d appreciate some help. I’m trying to create a script in Dynamo that would create an empty text parameter for all elements in a Revit model, which could then be manually updated with specific information in Revit, but I cannot find an appropriate node to do it.

For completeness, this is an exercise for creating a Dynamo script, and what I am trying to do is to create a script that could be given to a contractor on site, who would then run it on their copy of a Revit model. This would create the above blank parameter called “Construction Status.” The idea would be for the contractor to now update the parameter of the elements in the model with a not started, in progress, and complete text. The contractor would then rerun the script to output a CSV file with all the updated element status, which he would then give to me. I would take the CSV file and run a second script that would now colour code my copy of the model according to the status of the elements.

I’m new to all of this, so any help would be great!

Any reason you cant just use a project parameter assigned to all relevant model categories?
It should be a shared parameter if you need that data to be read by tags.
