FreeCAD is the worst. Thanks for building this!

Recent freecad is pretty decent. My main complaint these days is the performance of the geometry engine.

Awesome because you can build a model, expose the parameters, and allow web users to generate a model to fit their parameters.

Without context, it sounds like an FPS adaptation of a Dune game.

FreeCAD would benefit from effective

(1) agile Product Management,

(2) Product Design & continuous user-research,

(3) Improvements to test-driven development (TDD),

(4) transparent & open outcome-based roadmap,

(5) a vision to make the application easy to use for newbies in a maker-space, and (this is specific to my use-case),

(6) Improvements to the CAM module to make it easy to use this for CNC routers, and designing objects with sloped/curved surfaces.

- FreeCAD site: https://www.freecad.org/

- FreeCAD code: https://github.com/FreeCAD/FreeCAD

- FreeCAD forum: https://forum.freecad.org/

To echo others' comments: FreeCAD has improved significantly since v1.0, so I'm hoping this attracts quality & stability-minded develeopers, and a frequent release cadence.

I've been "vibe coding" with OpenSCAD with good results! OpenSCAD will automatically detect changes in the current open file and reload it, so I can use VS Code (with the OpenSCAD extension) to vibe code with Claude, and watch the changes appear on the OpenSCAD screen
