If you used 123D for precise, parametric mechanical design, FreeCAD is the open-source alternative. It is clunkier than 123D and has a steeper learning curve, but it runs natively on Intel and Apple Silicon Macs. It also has a "Mesh Remodel" workbench that can handle photogrammetry meshes (replacing 123D Catch).
The 123D suite was interconnected. You could use the 123D Catch app (which used photogrammetry to turn photos into 3D models) and import that geometry into 123D Design on your Mac for editing. This seamless workflow was attractive to hobbyists who wanted to replicate real-world objects.
If you are a Mac user looking for a replacement for the 123D workflow, you are in luck. The vacuum left by 123D has been filled by powerful, modern tools that run beautifully on macOS. 123d Autodesk For Mac
While users who already installed the application can still run the software offline on older Mac systems, it will not receive updates, and cloud features are defunct. Impact on macOS:
All 123D apps were 32-bit applications. Starting with , Apple no longer allows 32-bit apps to run. If you have a Mac running Ventura, Sonoma, or Sequoia, the 123D installer won't even launch. If you used 123D for precise, parametric mechanical
To understand the current landscape of 3D printing software, one must understand the legacy of Autodesk 123D. Launched around 2011, 123D was not just a single program; it was a suite of apps designed for the "maker" demographic.

, Autodesk officially discontinued all 123D apps, including the Mac versions. The 123DApp.com community and associated servers were taken down. Availability:
