is there a way to rename the comments in my lintel schedule? Im a bit stuck here
Add the Element.SetParameterByName node.
okay so that works. Now is there a way to rename all the empty cells in the schedule to t1,t2, t3 etc
By empty cells, are you referring to the headers for each grouping?
That should be doable via native Revit (it’s the Title, Count, Totals section).
