A 123DX file is a specific type of computer file format commonly associated with 3D modeling and design. It is primarily used in the context of 3D printing and rapid prototyping technologies. The "123" in the name refers to its origin from the software company Autodesk, which developed a suite of tools for 3D design and modeling, including Fusion 360. The "DX" stands for "Data Exchange," indicating its purpose as a file format for exchanging 3D design data between different software applications.

123DX files store detailed information about the geometry, topology, and material properties of 3D models. They can include data about the size, shape, and positioning of objects in the virtual space, as well as information on textures, colors, and other visual aspects of the design. This comprehensive data allows 3D printers and other related software to accurately interpret and recreate the model in physical form, layer by layer.

With the rise of 3D printing and its applications in various industries like manufacturing, healthcare, and architecture, the 123DX file format has become increasingly popular due to its versatility and compatibility with multiple design software platforms. Designers, engineers, and enthusiasts can share their creations easily using 123DX files, ensuring that their innovative ideas can be brought to life with precision and accuracy.

An OBJ file is a widely used file format in 3D computer graphics that serves as a standard representation for 3D models. It stands for "Object" and was originally developed by Wavefront Technologies. OBJ files store geometric data, such as vertex positions, normals, texture coordinates, and face information, describing the surface of a 3D object. This data is presented in plain text, making OBJ files human-readable and easy to exchange between various 3D modeling and rendering software.

The structure of an OBJ file is based on vertices (points in 3D space), which form the building blocks of the 3D model's shape. These vertices are organized into faces, typically triangles or quads, representing the surfaces of the object. Alongside the geometric data, OBJ files can also include material information, enabling the application of textures and shaders to the 3D model, providing it with color, reflectivity, and other visual properties.

Due to its simplicity and compatibility across different software platforms, the OBJ file format has become a popular choice for sharing 3D models. However, being a relatively basic format, OBJ files may not support complex features found in more advanced formats like animation data or high-level shader definitions. Despite this limitation, OBJ remains a widely adopted format in various industries, including gaming, animation, virtual reality, and 3D printing.
