ACAD 3D Block to Revit

I’m trying to send an AutoCAD 3d block to a Revit family. I followed the tutorial page, but the python code is giving me the following error.

Warning: IronPythonEvaluator.EvaluateIronPythonScript operation failed.
Traceback (most recent call last):
File “”, line 31, in
TypeError: ‘CoordinateSystem’ object is not subscriptable

Hey @chrisstaker welcome to our community forum!

That post and script are a bit old and things might have changed, what version of Dynamo & Revit are you using?
Any other edits to the script?
Could you share the stream with me so I can test it a bit?

Adding a link the tutorial as well: Mapping AutoCAD Blocks to Revit families with Dynamo

Revit 2020

Stream - Speckle

I had to access the basepoint slightly different.
