OpenScad to PythonScad conversion tool

[Matthieu Hendriks]

With a lot of help from chatgpt, claude.ai and notebooklm I created a conversion tool which reads a openscad file and convert it to a pythonscad file.

It's fully written in python and there are a few dependencies wich are easy to install with pip

for example 

pip install lark

pip install pprintp

and maybe some others

usage:

python s2p.py design.scad design.py

It passes the first test. The lark definitions where the most difficult ones.

There will probably still some bugs :)

Upload the file to claude.ai, add the errors or tell whats wrong, include a reference to https://pythonscad.org and most of the time he is able to fix it.

Maybe this tool will make the switch for the openscad designer to pythonscad easier

Hey Matthieu,

This is great stuff, I love it!

Please bear in mind: the s2p.py script does not include the final show() command.

You need to  show() the result to see something in the 3D view.

Another viable option to convert scad to python is:

open the SCAD file in pythonscad

Select  Design->Display Python Conversion

but it's not perfect either.

I'll give it a thought, normally I use a naming convention like print_module for all components to show and a separate script to finalize this, like

objs["o1"]=print_o1()

...

show(union(objs))
