@SeanP Thanks. So Invisible is a GraphicStyle?! Looks like the Archilab node is using a different method instead of the FilteredElementCollector, hence why it is different.
With the invisible graphic style, I then needed to set the filled region perimeter. Filled regions don’t have a Line Style parameter so needed to use a different method. The Plissken package had this python code which works:
