Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

FreeCAD User Book (2019)
I used to like OpenSCAD for its simple approach but then I discovered SDF-based modelling with Python made possible with this neat library: [1]. This is perfect if you are a programmer that doesn't know anything about CAD-Software.

>these the the central core that understands BREP and implements the geometric operations.
I've seen people quote a good modern CAD kernal as a 100 man year project. It's probably not going to happen, maybe there's some avenue for government funding?
Alternatively Signed-Distance-Functions are pretty nice. They're not BREP, but they're a lot easier to implement, and it might be possible to shove them into a BREP-shaped hole.
Here's a signed-distance-function based CAD kernal written in a few thousand lines of python+numpy, that seems to be about as fast as openscad. Maybe faster. https://github.com/fogleman/sdf

Signed distance functions in 46 lines of Python
Excellent. You might be interested in a Python library that I wrote for generating 3D meshes (STL files) from SDFs : https://github.com/fogleman/sdf
It just uses marching cubes for triangulation but the SDFs are all numpy'd and the SDF is evaluated in batches on multiple threads so it's relatively fast.

I used the SDF repo by Michael Fogleman. Check out his website, there's a ton of useful stuff on there. He contributes a lot to the open source community and has been mentioned in r/PlotterArt before.

10 ways to get the best out of OpenSCAD
Try out fogleman/sdf[1]. It is like OpenSCAD in many ways but the distance field model gives you offsets and fillets more easily.

Holy crap, why have I not seen this before?!?!!? I was even planning to start coding something like this myself. This is awesome!
- I am planning on creating a programming language for my Informatics Bachelor Thesis. What are your ideas for such a project?

Procedural CAD Modelling tools for WebGL
then there are 2 others, sop/CSGboolean and sop/CADboolean. CSGBoolean is indeed based on CSG, and uses jscad. And the CAD one (which I show in the video in this post) is based on opencascade, which is the most powerful/stable. Then the output of both of those nodes is converted to threejs in order to be displayed in webgl.

Is there a way to share a network drive or a folder over the internet?
That being said, https://github.com/jscad/OpenJSCAD.org sounds like a winner for your requirement of NOT having to download a file across the internet.

Show HN: Replicad, the Library for CAD in the Browser
this looks very nice. i think i like the ergonomics of your library... the "sketch on a plane then extrude" workflow feels nice and familiar.
could you compare and contrast replicad to JSCAD (https://openjscad.xyz)?
the examples in your docs are quite sluggish to load in Safari, but the workbench is very snappy!

10 ways to get the best out of OpenSCAD
No one has mentioned OpenJSCAD, which is the same idea in Javascript: http://openjscad.azurewebsites.net/

A fairly substantial rewrite is underway, the V2 branch linked above.

Code CAD – Use code to create CAD models
- Browserify to bundle the design into a website. Directly from the source CAD files, without rendering to a huge mesh file format.
It's cool because you get access to the whole javascript ecosystem, and it's native to the browser.
