Can someone tell me why this script fails? I’m running the latest versions of Windows 11, Revit 2024, pyRevit, and RevitPythonShell (r.i.p.). The following bit of code runs just fine in RPS, returning a dict of FloorType objects with their names as keys. However, when I run it in pyRevit using a pushbutton, I get an AttributeError indicating that the FloorType objects have no attribute Name (this also happens in Revit 2025). I know for a fact that they have this attribute, so I’m wondering if they got inadvertently wrapped in some other object without that attribute.
from pyrevit import HOST_APP
from pyrevit import DB
doc = HOST_APP.doc
floor_types = (DB.FilteredElementCollector(doc)
.OfCategory(DB.BuiltInCategory.OST_Floors)
.WhereElementIsElementType()
.ToElements())
floor_types = {floor_type.Name:floor_type for floor_type in floor_types}
Error Output:
IronPython Traceback:

This one has me stumped. I’m wondering if I’m just missing something obvious. (And I even tried rebooting my machine.)
Thanks all for your time.
