Hi Daniel, I’ve tried your suggestion and probably haven’t understood what you you mean… this is where I’ve got to now
the pink area is where I am trying to replace all value of the Fire Rating NB Parameter that are NULL (that’s what’s reported in the list) but could be an empty strung as another member mention.
the yellow area is where I’m trying to select all Walls and Doors on a chosen Level - can’t get this to quite work. If I only select on Category and attach that, then it works. but the moment i try adding 2 categories. yellow warnings
I’m sure this is so simple to resolve - bu still so new to Dynamo.
I really appreciate any help from anyone on this one.
PS also tried this version which looks for empty strings. Again is finds the walls, but doesn’t replace the empty string with a default value.
