123D Design
123D Design is Autodesk's free 3D modelling and CAD application for macOS, aimed at hobbyists, students, makers and small businesses who want to design and visualize 3D objects without the complexity or cost of professional CAD software. It lets users create, edit, and prepare 3D models for 3D printing, export designs in multiple formats, and view models in real-time. The app is popular in educational settings and among makers working with 3D printing technology.

1 suggestion123D Design has not received meaningful updates from Autodesk in several years and no native Apple Silicon build has been released. The app continues to run under Rosetta 2 on M-series Macs today, but Apple is removing Rosetta in macOS 28 (September 2028), so 123D Design will stop launching entirely on that release. You should begin evaluating alternatives now. Autodesk Fusion, the successor to 123D Design, is actively developed, runs natively on Apple Silicon, and is free for non-commercial use, students and educators — it offers substantially more features and better long-term support. LibreCAD is a capable free open-source alternative with a steeper learning curve. If you have existing 123D Design projects, export them to standard 3D formats (.obj, .stl, .step) sooner rather than later so they remain usable in whatever tool you migrate to.
