Hi! I am also following your amazing video: https://www.youtube.com/watch?v=PfCn7OrY_-A&list=PLc_1PNcpnV5742XyF8z7xyL9OF8XJNYnv&index=3

But I got stuck at the first line: 'cl = FilteredElementCollector()'
As I keep getting the message 'Exception : IronPython.Runtime.UnboundNameException: name 'FilteredElementCollector' is not defined'

It works though, if I switch the startup script to init.py and simply add 'doc = revit.ActiveUIDocument.Document' as the first line of the code. It seems like there is something wrong with the code posted here. I would be glad if you could help

I had the same issue and it worked for me when I selected the elements in Revit and then opened the RevitPythonShell.

@DanailMomchilov
I also solved the 'Exception : IronPython.Runtime.UnboundNameException: name 'FilteredElementCollector' is not defined' error by changing the import lines to:

from Autodesk.Revit.DB import *
from Autodesk.Revit.UI import *

add the following lines starting from line11

from Autodesk.Revit.DB import *
from Autodesk.Revit.DB.Architecture import *
from Autodesk.Revit.DB.Analysis import *

Don't do this

from Autodesk.Revit.DB import *

It's bad practice. Always use the namespace to point to the type you want e.g. DB.FilteredElementCollector

i faced an issue, can you help me in this.

#######OK NOW YOU CAN CODE########

Paste this on top of your script
Your code is using a variable called 'doc' but it was not defined before.
Go through this site https://dynamopythonprimer.gitbook.io/dynamo-python-primer/getting-started/boilerplate-setup-code
it will go over some basics on getting started

i ask the chatgpt, and the i pastet the code"# -- coding: utf-8 --
from Autodesk.Revit.DB import *
from Autodesk.Revit.UI import *
doc = revit.ActiveUIDocument.Document
uidoc = revit.ActiveUIDocument" on the top, and i solve the problem
