Is there a text page (say on GitHub) for folks who have trouble following
videos?

You can try it now. The steps are shown at the start of the video.
Caveat: not all OpenSCAD primitives are properly implemented yet, so YMMV.

This is kind of an abandoned project (last commit 6 yrs ago) AFAICT and
I"m not sure it still works with current versions of Blender.
I should give it a try, but I suspect it won't work with Geometry Nodes,
which is the modern way Blender does geometry.

This one is simply a Blender add-on that calls OpenSCAD, gets it to
produce an STL model and loads it into Blender.

Neither project seems to offer a true integration of OpenSCAD into
Blender, meaning a solution where we can do away with the existing OpenSCAD
UI entirely and use Blender as the native UI for OpenSCAD.

In particular, I'd like to make the full parametric experience OpenSCAD
provides, and especially the [code -> view result -> code -> view result
...] design loop fully within Blender without ever having to use external
tools.

The scad2nodes experiment (which is just that, btw: an experiment) is part
of a larger effort called geometry-as-code I'm trying to build into Blender
(I've posted about this before, see demo vid here:
https://www.youtube.com/watch?v=aZq8ZlmqHJo

Which tool would one use for what circumstance and why?

If I ever get around to finishing 'Geometry-As-Code' in Blender, hopefully
you won't need anything else :)

Cheers,

Hi Folks,

If you're enjoy both OpenSCAD and Blender like I do, here's a fun little
experiment I've coded over last week-end:

https://github.com/emogenet/scad2nodes

TL;DR:
- it converts an OpenSCAD model to a tree of geometry nodes in Blender
- at this stage, it is just an initial experiment, and not all
OpenSCAD primitives are fully supported.

Enjoy (if you are into these kinds of things).
