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.

Plot of triangle mesh with py5
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?

Updates to the Fusion 360 Simulation Workspace
I'm aware, however there have been a couple efforts now to introduce CAD tooling into Blender.
https://github.com/hlorus/CAD_Sketcher
https://github.com/EleotleCram/blender-cad-tools
I'm not suggesting that they are ready for professional use, just that I don't think the Autodesk moat is as deep as some might assume, and that if there was a concerted community effort Blender could accomplish those tasks.

Reproducing a garden from a plan?
You can use CAD Sketcher to work with precise measurements and constraints within Blender.

Is anyone able to explain what the heck is happening here? I've made this 3-4 times now, starting with a fresh file with the same results each time.
I'm hearing from "Hlorus" that this is actually a regression of a bug in CAD Sketcher https://github.com/hlorus/CAD_Sketcher/issues/225 Thanks for trying to help guys.

What are the most distributed, community-driven open-source projects that have been successful?
I haven't tried it out yet but here's the plugin CAD Sketcher for blender, worth checking out https://github.com/hlorus/CAD_Sketcher
- Constraint-based geometry (CAD) sketcher for Blender
- There for sure has to be a file somewhere?
