Autodesk 123D

Autodesk 123D was a suite of free digital design tools aimed at hobbyists and makers. It allowed users to create 3D models, design prototypes, and even prepare designs for 3D printing. The software included various applications, such as 123D Design for modeling, 123D Sculpt for organic shapes, and 123D Catch for turning photos into 3D models. Although Autodesk discontinued 123D in 2017, it was significant in making 3D design more accessible to everyone, encouraging creativity and innovation in fields like engineering, architecture, and art.
