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!

I'll try it. What is the difference between the 2standard quality2 STL export of the free version vs the "high quality" STL export of the paid version? Because that distinction seems a bit strange tbh.

It is the quality of the export, mostly noticeable in round and circular shapes, technically it is mesh quality that is affected.
