U3D 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.


STP STandardized Exchange of Product File

A widely adopted file format for the exchange of 3D data across diverse computer systems, including CAD, CAM, and CAE applications. Designed to ensure seamless interoperability, STEP files provide a reliable and standardized method for sharing complex 3D models.

Key Features of STEP/STP

  • Universal Interoperability:

    As an ISO-standardized format, STEP files eliminate vendor lock-in, allowing smooth data exchange between major CAD software like SolidWorks, NX, Creo, CATIA, and more.
  • Broad Compatibility:

    Supported by numerous applications and platforms, STEP files simplify cross-industry collaboration and ensure consistency across different workflows.
  • High Accuracy:

    Unlike mesh formats such as SKP, OBJ, or STL, which may introduce distortions, STEP files maintain the precise shape, dimensions, and integrity of 3D models.
  • Materials:

    STEP/STP files retain color information per assembly, making them useful for design visualization. However, they do not support transparency (alpha component), meaning transparent materials will appear opaque.

STEP/STP File Conversion

STEP files can become quite large, particularly when they contain intricate or high-resolution 3D models. To reduce file size, our Autoconverter software offers an efficient solution by utilizing the faceted BREP representation, which can reduce file size by up to one-third. Leveraging the powerful Open Cascade framework, Autoconverter ensures full compatibility with the latest STEP standards, making it the ideal tool for optimizing STEP files without compromising quality.
