[Error] Hello friends, I’m trying to modify the slop value of each pipe in the list. But the dynamo is showing the warning, would appreciate if someone shed some light. I’ve searched on the internet already but I’m not getting its solution. Appreciate the help. Thank you

Element.SetParameterByName operation failed. The parameter is read-only

Unfortunately you can’t. However you can add slope in your Geometry before you create pipes in Revit.
