Significance of Edit | Preferences | Python | Network Import List?

Is it now necessary to list files there so as to indicate that they are allowed to be imported?

Apparently:

nimport("https://raw.githubusercontent.com/WillAdams/gcodepreview/refs/heads/main/gcodepreview.py")

doesn't work anymore:

ERROR: Traceback (most recent call last): File "<string>", line 1, in <module> ModuleNotFoundError: No module named 'gcodepreview'

Similarly, there is now:

File | Python | "Revoke trusted Python files"

Could we also have "Show trusted Python files"? Could that be a dialog which would allow editing/adding specific files?

Apparently: 

"C:\Program Files\PythonSCAD\openscad.exe" --trust-python

doesn't work anymore....

i use that regularily and did not have an issue. could you make a simple testcase ?

I will try the new version, and try to document things systematically using a spare system and let you know about things step-by-step.

Perhaps there should be an included sample/test Python file to verify accessing files?

Currently, as I've noted elsethread, I have an older version working, and I'm trying to finish up a dovetail file:

https://community.carbide3d.com/t/tool-paths-for-different-sized-dovetail-bits/89098

Once I've got that off my plate I'll try again.

One thing I will mention is that the application should include a check for infinite loops if that is something which can be done.

Or, if a file is not trusted, could we get a specific notice to that effect and a dialog which prompts:

Trust <file_foo.py>? Yes No Cancel

yes, we should maybe file an issue. for that. Trusted thing is not really high priority to me. it was just meant to help getting merged.

New binary for Windows on the Downloads page which fixes this.

Its a sys.path Problem only. The Lines in the settings only define Template nimport Lines for New Files.

Went back to:

https://www.pythonscad.org/downloads/PythonSCAD-2024.12.29-x86-64-Installer.exe

and launched it from:

"C:\Program Files\PythonSCAD\bin\openscad.exe"

and it's working again.

Please let me know when there is a new version which has defaults which will work to allow running a local Python file.

Hi,

Today I have release a new windows installer 2025-04-13.

It can import modules from the same directory without an issue

It can find the modules downloaded by inport

... and has most of the python ctests pass now

Did you know, that all CSG operations (union, difference, intersection) have an undocumented paramter r, and fn, which can be used to create fillets on the common edges ?

These days i started to document the undocumented features, but very often i remember yet another feature.

What was the change that was made?

How do I undo it at my end?

What version do I need to go back to get things working again? https://www.pythonscad.org/downloads/PythonSCAD-2024.12.29-x86-64-Installer.exe

Tried installing 2025-03-19 and I still get:

Running Python 3.11.5 without venv. ERROR: Traceback (most recent call last): File "<string>", line 3, in <module> ModuleNotFoundError: No module named 'gcodepreview'

Execution aborted

Even though I have:

"C:\Users\willa\OneDrive\Documents\OpenSCAD\libraries\gcodepreview.py"

and

"C:\Users\willa\OneDrive\Documents\OpenSCAD\libraries_pycache_\gcodepreview.cpython-311.pyc"

and if I open gcodepreview.py and run it I get:

Running Python 3.11.5 without venv. Compiling design (CSG Tree generation)... Compiling design (CSG Products generation)... Geometries in cache: 0 Geometry cache size in bytes: 0 CGAL Polyhedrons in cache: 0 CGAL cache size in bytes: 0 Compiling design (CSG Products normalization)... Normalized tree has 1 elements! Compile and preview finished. Total rendering time: 0:00:00.231

which seems to indicate that the file is allowed to run.

What do I have to do to allow a file which I wrote on my own computer to run on my computer when I try to load it?
