karotte, 
So… I'm writing another piece of CAD software 🤓
Say hi to Dune 3D, a parametric 3D CAD that supports STEP import, chamfers and fillets!
It's the result of gluing together the UI from Horizon EDA with the solver from solvespace and Open CASCADE for a geometry kernel.
After about 3 months of off-and-on development, it's finally ready for prime time, go check it out on https://github.com/dune3d/dune3d#readme
Don't be surprised if it's a bit janky or lacks some features, there's still a lot left to be done…
