What is an 123DX file?

The .123DX file extension is associated with 123D Design, a discontinued 3D modeling software developed by Autodesk. This file format was used to save 3D models created within the application, encompassing a variety of geometric shapes and design elements.

More Information.

123D Design was first introduced by Autodesk in 2011 as a part of the Autodesk 123D suite. The software aimed to simplify the process of 3D design for users without a professional background in CAD. The .123DX file format was designed to store 3D model data, including shapes, materials, and configurations, allowing users to save and share their projects.

Origin Of This File.

The .123DX file format originated with Autodesk’s 123D Design software, which was part of the Autodesk 123D suite of 3D modeling and CAD tools. Autodesk released 123D Design to provide an accessible and user-friendly platform for hobbyists, makers, and educators to create 3D models.

File Structure Technical Specification.

The .123DX file is a proprietary binary format that encapsulates the entire 3D model, including its geometry, textures, materials, and scene configurations. While the exact specifications of the binary format are proprietary to Autodesk, the file typically includes:

Header Information: Metadata about the file version and software.
Geometry Data: Detailed information about the 3D shapes, including vertices, edges, and faces.
Materials and Textures: Data regarding the materials and textures applied to the model.
Scene Configuration: Information about the scene setup, including lighting and camera positions.
