Eto + python + mac. shut down

이신후 · May 21, 2025, 1:50pm

Hello. Recently I noticed about Eto. I started to study this and connecting my python project to this UI.
But in some cases the bug not just break process, but also break Rhino. What I mean is that, in some cases Rhino shut down.
I had to open Console App to check the last error messages. Why this happened? And How can I fix this?

Hello @이신후 is Rhino crashing when you’re editing python in the Script Editor?

Because Rhino Crash. I have to check error message thorugh Console App in Mac.
This makes development experience so bad. So I want to fix this.

이신후 · May 22, 2025, 12:44am

This is image of UI I’m trying to build.
If i click Upload Button, if there is any error in code(simple error such as input value count not matching). Rhino Crash.

이신후 · May 22, 2025, 12:51am

If there is better way to create GUI, I want to try, please inform me.
functions that I need with the GUI

interact with User
user click RhinoObjects > check Validation + Create BlockDefinition > simulate and optimize with the Block Definition > Visualize 3D results and show data with table or graph.
Python (Cpython prefer)
Various UI elements(image, table, Rhino viewport)

the reason I choose Eto was that Eto has all of this functions, but if there is other way, I want to try that.
Thank You for reading this!

CallumSykes · May 22, 2025, 11:49am

Hey @이신후 ,

A few questions.
Can you run the _systemInfo command and paste the results here.

I can’t test the script crash unfortunately without this library, if you can add it here ot DM it to me I can try to replicate and then create a ticket.

I personally write my Eto UI’s in the Script Editor.

I do know that some things will just Crash Rhino when scripting, especially events.
try/catch can help with certain errors to prevent crashes.

Also, more Eto docs which may help.

Are you able to include me this library either here or in a direct message @이신후? The script won’t run without it for me

이신후 · June 10, 2025, 2:21am

RhinoPlugin.zip (156.3 KB)
This is all files in that directory. I ran codes in python_scripts directory.
Thanks for follwing up.

tom33 · June 10, 2025, 3:40pm

The rhino ide can now write c# directly. If you want to use pyeto, it is better to write py+cs in the rhino ide. There should be fewer errors.

nathanletwory · June 10, 2025, 3:55pm

@이신후 for what it is worth, the screenshot of the Console app shows the error and solution. __init__() missing an argument core_inputs. You probably should do core_inputs=core_inputs, but it really depends on what the __init__ of your class ApartmentInputStructure is.

edit: I actually only now noticed the ZIP file you uploaded. I think probably should remove the named arguments in the call, just pass in the values you want to without naming them.

From

        apartment_input_structure = ApartmentInputStructure(
            apartment_name,
            unit_inputs,
            core_inputs,
            corridor_inputs=[],
            window_inputs=window_inputs,
            sidewall_inputs=[],
        )

to

        apartment_input_structure = ApartmentInputStructure(
            apartment_name,
            unit_inputs,
            core_inputs,
            [],
            window_inputs,
            [],
        )

@N Thank you for the advice. I’m trying to find best way to build interface with Rhino - python script.
I used to build this interface with grasshopper + VSCode Studio and make every python scripts as package and import + reload in Grasshopper to make my codes reusable.
But my client had some difficulties to use GH interface so I wanted to build UI in Rhino.
What is the best way?
My concern is two things.
First, it should be flexible and interactive with rhino Document(like creating block defintions or validating)
Second, the code could be reusable(I build many tiny utilty codes and use those codes in many projects)
I found that I can write python3 in rhino script editor(before I confused script editor between RhinoPythonEditor which allows only iron python), so I started to test it. But if there is better way, please give me some advice

이신후 · June 11, 2025, 12:47am

Thank you for your check.
I knew my code has error, my issue was that Rhino crashes so its hard to check what the error is, which makes developing experience so bad.

As you mentioned, I will try to remove named args to check if this work. Thank you!
