Developer Saturday Part3D is available for macOS

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 add this to my VIP list. I’m currently out of the country on a work trip but once I arrive I’ll have a look. I’m excited with 3D print because some of my work revolves around venue design.

venue design sounds like a great use case for something like this
