Hi, in order to create a wall between two levels I set levels that based on the project levels with a decrease of 90.
the problem is that these levels created in Revit project and I want to delete them.
I understand I can use the passthrough to delete the levels after I use them to create the walls.
I could not find the way to use this node properly.
in the blow picture the levels I want to delete with the difference of 90.
