FreeCAD
This is the official source code of FreeCAD, a free and opensource multiplatform 3D parametric modeler.
Project mention: Ask HN: What Are You Working On? (February 2025) | news.ycombinator.com | 2025-02-23I'm a long-time FreeCAD user, and one of my annoyances is that long-running operations lock up the entire UI and can't be aborted.
So for my first contribution to FreeCAD I'm working on fixing this.
The underlying CAD operations are done by "OpenCascade", and at first I thought OpenCascade had no support for aborting operations part of the way through. So my first implementation was to move the operation into a child process and give the user a dialog box that would allow terminating the child process.
But it actually turns out OpenCascade does support aborting the operations! So now I'm working on doing it the OpenCascade way.
My PR is here: https://github.com/FreeCAD/FreeCAD/pull/19796

atopile
Design circuit boards with code! ✨ Get software-like design reuse 🚀, validation, version control and collaboration in hardware; starting with electronics ⚡️
Project mention: I Designed My LED Matrix PCB with Code Instead of Traditional EDA Tools | news.ycombinator.com | 2025-04-25Atopile is another thing in the circuits-as-code space: https://github.com/atopile/atopile
As a half EE/half SWE I think there are significant benefits to circuits as code but I'm not impressed with this one. Atopile has a narrower focus (autorouters are really really hard) and doesn't use as many buzzwords. Like why on earth does a "web first approach" matter at all for hardware development?
But also, GUI tools are getting better, Kicad 9 had a lot of changes that made templating / reusing blocks easier. And it works fine if not great with version control.
I don't see circuit-as-code taking off with humans anytime soon, it's much better but not enough better to convince EEs many of which don't code or at all. But I can see it becoming much more common as LLMs get better at complex circuits.
