Hello,
as per title, I wish to remove any sheet collection from some sheets.
However, passing to the Set Parameter node null (or an empty string) does not work…
Any way to do this?
thank you
The Sheet parameter is read-only. It’s the SheetCollection class that controls which sheets it contains and, unfortunately, it seems like the API doesn’t yet contain methods for adding or removing sheets.

Hi @gsucciXHCQR you can try as here and see if it could work for you

I stand corrected! Not sure what this is in reference to then:
The read-only parameters Sheet Collection and Referencing Sheet Collection are available for compatible view types in Revit, alongside the existing sheet and view parameters.

This works, thank you!
ViewSheet.SheetCollectionId is the parameter which gets/sets the collection by element id, set to ElementId.InvalidElementId to reset
