123D is not available for Linux but there are plenty of alternatives that runs on Linux with similar functionality. The best Linux alternative is Blender, which is both free and Open Source. If that doesn't suit you, our users have ranked more than 50 alternatives to 123D and 19 are available for Linux so hopefully you can find a suitable replacement. Other interesting Linux alternatives to 123D are FreeCAD, MakeHuman, Wings 3D and Autodesk Maya.
A comprehensive open-source 3D software suite for modeling, UV unwrapping, texturing, rigging, and animating. It supports renderings, simulations including fluid and cloth dynamics, complex compositing, video editing, and Python scripting, running across all major operating systems.
A powerful open-source parametric 3D modeler ideal for mechanical engineering, supporting Python scripting, running on Windows, Linux, and Mac, with modular architecture allowing extensive adaptability and use with scientific computing libraries.
Free interactive open source software for swift creation of customizable 3D human models, featuring precise morph controls, realistic pose simulation, real-time editing, multi-platform export, and support for body, facial, and garment customization in many animation pipelines.
Wings 3D is a subdivision modeler inspired by Nendo and Mirai from Izware.
It is possible to assign materials, vertex color, UV coordinates and textures, but there will be improvements in those features before Wings goes 1.0.
There is no support in Wings for doing animations.
Professional-grade 3D modeling, animation, rendering, and visual FX software used in films, TV, and games, featuring advanced tools, Bifrost effects, and a visual programming environment for intricate simulations.
