I have a schedule of generic annotations to inform material tagging in Revit. I have pulled type parameters from the generic annotations to excel in order to write them and push back from excel. Works great except I want some of the values to be blank. Problem is if there is already a text value in the type parameter I cannot make it read as blank unless I put an “NA” or “0” Value in to overwrite it.
How do you clear a family parameter back to zero?
