I'm a huge Solvespace fan so you had me at fillets and chamfers! Thanks for posting this.
Played around with Dune 3D and so far some cool stuff compared to Solvespace is:
- Chamfers and fillets (seem to work well so far)
- Groups can be reordered! This is huge for workflow and managing bigger designs.
- There's a cool shortcut search menu if you hit spacebar.
- According to the README, it solves some stuff symbolically, which should be good for performance (hopefully it'll have fewer weird cases than Solvespace where the solver has trouble)
The UI needs some work, and there's some basic functionality like STL export that I could only find from the spacebar search menu, but this is an amazing start and I hope this project grows. I need to design a simple widget for 3D printing in the next couple of weeks and I will definitely be trying this for that.
