🐞 Description of the bug

Somehow the import crashes, if I use a rhino model with a newer rhino file version (Rhino 8). I can import the model with Discovery, SpaceClaim and PyPrimeMesh. I get the following error message:

File ...\lib\site-packages\ansys\geometry\core\errors.py:98, in protect_grpc.<locals>.wrapper(*args, **kwargs)
     96     out = func(*args, **kwargs)
     97 except (_InactiveRpcError, _MultiThreadedRendezvous) as error:  # pragma: no cover
---> 98     raise GeometryExitedError(
     99         f"Geometry service connection terminated: {error.details()}"
    100     ) from None
    102 if threading.current_thread().__class__.__name__ == "_MainThread":
    103     received_interrupt = bool(SIGINT_TRACKER)
GeometryExitedError: Geometry service connection terminated: Operation failed.

If I convert the Rhino 8 file to Rhino 7, the import works fine. A better error feedback would be helpful.

📝 Steps to reproduce

Use a rhino 8 file for import

Thanks @dkowollik! Let's clarify the scenario if possible :)

Under what conditions is this failing? I am assuming Ansys 24R2 products, specifically the Geometry Service, and via PyAnsys Geometry - right?

Have you tried it using PyAnsys Geometry and Discovery or SpaceClaim? And in that case, does it work? Or have you only tried it using the products in standalone mode (i.e. not through PyAnsys Geometry, but through the traditional GUI)?

[dkowollik]

If I use the traditional Discovery GUI the error does not occur.

The error occurs, if you use the below python snippets:

from ansys.geometry.core import launch_modeler_with_geometry_service
modeler = launch_modeler_with_geometry_service()
model = modeler.open_file('Named_Selection_Rhino_8_Example.3dm')
File C:\Python\Python310_64_ansys\lib\site-packages\ansys\geometry\core\errors.py:98, in protect_grpc.<locals>.wrapper(*args, **kwargs)
     96     out = func(*args, **kwargs)
     97 except (_InactiveRpcError, _MultiThreadedRendezvous) as error:  # pragma: no cover
---> 98     raise GeometryExitedError(
     99         f"Geometry service connection terminated: {error.details()}"
    100     ) from None
    102 if threading.current_thread().__class__.__name__ == "_MainThread":
    103     received_interrupt = bool(SIGINT_TRACKER)

GeometryExitedError: Geometry service connection terminated: Operation failed

If I use the Python Discovery interface a different error occours. Here the new error occurs also for Rhino 7 files.

modeler = launch_modeler_with_discovery(hidden=True)
model = modeler.open_file('Named_Selection_Rhino_8_Example.3dm')

Okay, I will bring this to the server/product development teams. Seems like we might have an issue. Thanks for opening this @dkowollik
