Hi, I have a parameter that many elements (views) doesn’t have, so I want to put these parameter on elements only that dont have value but I have other value that I dont want to change, so my logic said that I have to filter only the elements that have no value. Thank you!
hi,
here is a possibility especially if you do not have a value of your parameter in the form of a string

Thank you so much Christian, I did it succesfully.
But at the end how can I put a parameter in the “in” element? I tried this but doesnt work

Your filter node looks like you might have it wired with the input as your string list (it’s previewing as all blank). Your list input needs to be the initial list of elements.

“No value” is really just an empty string, so you can just check if val == "";

if you analyze your error message, you send string instead of Revit.Elements (confirm with your mask which displays your values) plug your elements into the input list of the filterbyboolmask

What do the errors say? The errors will typically tell you what the issue is. Do all elements have that parameter? Right now you’re filtering for all the elements who have no value. Is that what you want?
