OpenScad to OpenJSCAD fails

[TeslaGeek]

Hi, I have installed the CLI version on Mac and as far as I can tell everything is installed OK. However firstly, when I run openjscad example005.jscad from the terminal nothing happens. Secondly, the CLI does not allow me to choose an scad file from a local hard drive and thirdly if I have an openSCAD file, how I can convert it to OpenJSCAD ?

@TeslaGeek Welcome!

The script places the converted file into the same directory as the original. So, please look inside the examples directory.

If the script executes properly then a message about the Blob export size should show in the terminal.

If you still have issue then please run ./openjscad --version I'd like to see the output, if any.

It seems, openscad to openjscad still have some problem. I have tried the code below, it failed.
