U3D to OFF Conversion
Discover the simplest way to turn U3D into OFF using our powerful tool:
Install Autoconverter
Download and install Autoconverter on your system. Launch the software to convert U3D files to OFF format.
Import U3D File
Click Open... to load your U3D file (.u3d, .idtf), or drag and drop it into the application window.
Export to OFF Format
Use Save As... to export your file to the OFF mesh file format (.off).

Universal 3D File
An open standard for 3D data exchange, originally developed by the 3D Industry Forum to enable universal 3D visualization across platforms. As a compressed, binary file format, U3D efficiently stores three-dimensional triangular meshes along with additional properties such as color, transparency, or texture coordinates.
Key Features of U3D
- Open Standard: Royalty-free format maintained by ECMA International (Standard ECMA-363).
- PDF Integration: U3D enables the generation of PDF documents that contain interactive 3D data (ISO 32000). This means that you can view, rotate, zoom, and manipulate 3D models within a PDF document.
- Compact Size: Optimized compression for web and document embedding.
- Cross-Platform: Viewable across major operating systems without proprietary software.
U3D File Conversion
Our Autoconverter and Automesher Application utilize Intel's powerful open-source IFX conversion library to deliver robust U3D file conversion capabilities. This technology enables seamless two-way conversion between the U3D format and various industry-standard 3D formats including STL, OBJ, SKP, DAE, STEP, IGES, DWG, 3DS, FBX and X3D. The solution provides reliable transformation of 3D data while maintaining optimal file structure and visual fidelity throughout the conversion process.
Object File Format
A straightforward, human-readable file format designed for representing 3D polygonal models. As a lightweight alternative to complex CAD formats, OFF focuses on storing essential geometric data - vertices, edges, and faces - without proprietary constraints.
Key Features of OFF
- ASCII Text Files: OFF files are text-based and use a simple syntax to store geometric data of 3D objects. The files can be easily edited and viewed with any text editor or viewer.
- Polygonal Shapes: The OFF format allows to store 3D triangles, quads, and other generic polygonal shapes. Each shape is defined by a list of vertices and a list of faces.
- Limitations: OFF files support only geometric data - materials, textures, and group names from source files are discarded during conversion.
OFF File Conversion
Our software offers two specialized approaches for OFF file conversion. Autoconverter handles conversion of OFF files to common mesh formats including STL, SKP, OBJ, and PLY, maintaining the original polygonal structure. Autoshaper provides advanced conversion of OFF polygonal data into smooth NURBS surfaces, exporting to BREP, STEP, and IGES formats for CAD workflows.
