With grateful thanks to Larry and his python script, we now have a windows executable to convert openscad routines to json files. For those on windows that are interested, I have put the executable up on my odds & sods web page for download- https://vk7krj.com/Odd_files/ In a cmd window, it's just-  mkjson [your openscad module.scad] [your preferred output file name]  using your .scad script as input and giving a name (without extension) for the output file. You do have to have python (I have used python 3.14.3) installed and in your windows path first. -- Cheers, Ken bats059@gmail.com https://vk7krj.com https://vk7krj.com/running.html ---------------------------------------- A baby can be defined as an ego with a noise at one end and a smell at the other.
