View.PermanentlyIsolateElement not working with curtain wall

Hi, I cant get the one curtain wall element to show in my elevation and hide all others. Thought View.PermanentlyIsolateElement would work but it takes away the crop region and dosnt hide other panels in the view. Any ideas?


Can you share a sample rvt and dyn. Think I know what is up here but need something to test with.

Needed to use at levels

Using at levels actually sort of worked. Its not hiding all the other curtain walls in view and it hides the curtain wall doors in the curtain wall. Not sure how to fix either of these things or if its just the node
