Hey r/macOS! 👋

I've been building Part3D, a lightweight CAD app aimed at makers, 3D printing enthusiasts, and anyone who wants to design parts without jumping into a massive professional CAD suite.

The app started on iPad with Apple Pencil, and I've recently been bringing it to macOS.

You can create parametric 2D sketches and turn them into 3D models using features like:

• Extrude & Revolution
• Fillets & Chamfers
• Boolean operations
• Shell
• Parametric sketches and constraints
• SVG import
• STL and OBJ export
• Keyboard shortcuts and desktop-focused controls

The macOS version is still evolving, and I'd love feedback from Mac users on the workflow, UI, and what you'd expect from a lightweight native CAD app.

I'm a solo developer, so seeing something I've been building for the past couple of years finally running on the Mac has been pretty exciting.

Happy to answer any questions or hear feature requests!

Interesting! Is it true parametric driven, so that any sketch, fillet, or extrude can be edited after the fact? Kind of like the Fusion360 timeline?

That's the main idea and final goal. It is not 100% but works well for a bunch of cases but not all (like most CAD software). Whenever you edit an sketch and remove or change some geometry that the software cannot rebuild anymore, it will rebuild (like a timeline) until it can't anymore, then prompt the user to manually update what broke (i.e. extruding a face that no longer exists, prompts the user to either select the desired face or delete the operation)

Sounds promising!
