Does python script have holes in it or do I need an import somewhere (that I amy be missing - am new to dynamo/python) I have a python code script I am trying to adapt from here: <span style=“color: #75715e;”>http://help.autodesk.com/view/RVT/2014/ENU/?guid=GUID-E7B451BB-21DC-4D72-AD26-75F0C2E911E4</span> It Bombs out at line 23 “<span style=“font-weight: bold; color: #f92672;”>for</span> objFace <span style=“font-weight: bold; color: #f92672;”>in</span> objRoomSolid.faces:”

Ron,

You have misspelled “Faces” in your code by spelling it like this: “faces”. That’s a syntax error.
