Hello,
i am using Zemax Optics Studio 23.1 and trying to run the python example files included in the “Zemax\ZOS-API Sample Code\Python” directory.
While others seem to work, when trying to run “PythonStandalone_23_ray_fan_native_manual_comparison.py” i get an error.
----
Traceback (most recent call last):

  File "c:\ex\PythonStandalone_23_ray_fan_native_manual_comparison.py", line 262, in <module>

    ray_settings.Field.UseAllFields()

    ^^^^^^^^^^^^^^^^^^

AttributeError: 'IAS_' object has no attribute 'Field'

Exception ignored in: <function PythonStandaloneApplication.__del__ at 0x000001D4F7E9F880>

Traceback (most recent call last):

  File "c:\ex\PythonStandalone_23_ray_fan_native_manual_comparison.py", line 72, in __del__

TypeError: 'MethodObject' object is not callable
----
I run the original file without any changes. 
Could somebody please possibly advise if eventually the API did evolve and this particular example file is no more compatible?

Best regards
Dimiter
