I would like to write a string to a Multiline Text parameter in Revit. With simple Element.SetParameterByName i am able to write something. But only the first line… 
What I want is to report the worksets name to a Project Info parameter which is a multiline text.
What am I missing? Help Community!?
Alright… I got it…
I missed a String.Join and a \n - voila…
Hope my post at least can help somebody else…
This works OK (make sure there is a space before the " \n"), but when I try and edit the values via Edit Type the data is one continuous string. I tried " \r" and that doesn’t work at all. Any ideas or is this a ‘feature’ of Revit.
Thank you, it helped me!! 
If you use “\r\n” you get the import as wanted. Works in Revit 2020
Nice @S.Arnbjerg !
And for info, works in Revit 2019 aswell, just tested it.
I did also add the space before, everything: " \r\n"
