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.

Gimp 2.99.18 Released: The Last Development Preview Before 3.0
OCCT is definitely difficult.
I am almost as far as you can get from an expert but:
For example the TNP issue derives from OCCT (or something in the stack close to it, I am not exactly sure) not really handling face naming at all.
So if you want to avoid topological naming issues (which is a hard problem in CAD), you apparently have to do some work to track before and after and reconstruct your face naming.
https://wiki.freecad.org/Topological_naming_problem
https://forum.freecad.org/viewtopic.php?t=27278
Then there are various fairly entrenched issues to do with filleting and chamfering. Basically, both these operations will fail (in FreeCAD at least, but it's OCCT at "fault") if a chamfer or fillet would completely consume an existing edge. (It also sometimes creates impossible objects when filleting, or used to).
Booleans can be slow.
And more generally, it seems if you track the FreeCAD project that OCCT can be inscrutable when things fail; error messages aren't the greatest etc.
The flip side of OpenCascade is that it seems to be highly portable and has for example been compiled to JS with Emscripten for this astonishing thing:

It's a monumental open source project, for sure, and it's definitely not nothing that we have an open source CAD kernel; these are projects that perhaps have to extend beyond the working life of an individual developer if they are to be stable. And there are loads of projects built around it.
- Better OpenSCAD?

Show HN: Dslcad a programming language and interpreter for building 3D models
If you haven't seen it you may want to check out https://github.com/zalo/CascadeStudio
From what I see, it is exposing the OpenCascade base commands directly, versus your completely new DSL, but you might be interested in a way to implement your DSL on top of such an interface such as this which takes out a lot of the extra work of having a rendering interface, exports, etc, maybe.

Ask HN: If money was no object what software would you create?
It's nowhere near ready for primetime, but you should take a look at CascadeStudio (https://github.com/zalo/CascadeStudio)

Fornjot – The world needs another CAD program
FreeCAD is GUI-based though, not code-first like Fornjot. A better comparison would be CadQuery (https://cadquery.readthedocs.io/en/latest/intro.html) or Cascade Studio (https://zalo.github.io/CascadeStudio/), both of which are code-first and based on the same CAD kernel as FreeCAD.

Support for Javascript?
It is an actual example from CascadeStudio, but I haven't looked into it enough to know how what actually happens under the hood, but I assume the following:

cadCAD alternative for Go?
Object Oriented Programming is a way to go to create CAD tool for school project, not golang (too hard for school task). If you really must, this was I want to try in one of my projects: https://github.com/deadsy/sdfx

3D Printed fightstick
Designed all of these parts* using Deadsy/SDFX, it was certainly interesting and I enjoyed working with it, getting visual artifacts off my model and keeping file sizes down is a bit tedious though.

SolveSpace – parametric 2d/3D CAD
I wrote this (in golang) to satisfy my need to generate STLs for 3d printing.
https://github.com/deadsy/sdfx
In general I like to write code to define objects, but there are some situations where a graphical editing UI would be nice. ie- Curve and polygon design.
You can sort of imagine a hybrid approach where you could crack open a mini editor to design a curve and then use it to generate code (table of numbers) which you could then extrude/sweep/loft or whatever.

Curated Code CAD
Nice to see sdfx [1] there, this project is impressive.
deadsy built some rather sophisticated models, be sure to check out the renderings in the github README!

What free CAD software should I use for precise designs for a 3d-printer?
I had a similar question, and this is how I answered it (after a visit to openscad,,,) https://github.com/deadsy/sdfx
What are some alternatives?
cadquery - A python parametric CAD scripting framework based on OCCT
sdf - Simple SDF mesh generation in Python
psml - Python library for OpenSCAD
opencascade-emscripten-port - Open CASCADE - Emscripten / Webassembly port
OpenJSCAD.org - JSCAD is an open source set of modular, browser and command line tools for creating parametric 2D and 3D designs with JavaScript code. It provides a quick, precise and reproducible method for generating 3D models, and is especially useful for 3D printing applications.
