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.


3DS 3D Studio File

A widely recognized format used for storing 3D polygonal mesh models, originally developed for Autodesk 3D Studio. Known for its broad compatibility and straightforward structure, it remains a popular choice for real-time visualization, gaming, architectural modeling, and lighting design despite its legacy limitations.

Key Features & Capabilities

  • Extensive Support:

    The 3DS format supports model naming conventions, reusable geometry instances, and material definitions including transparent colors and texture mapping. Its hierarchical structure preserves object relationships and basic animation data.
  • High Compatibility:

    3DS files work with most major 3D software including DIALux for lighting design, Blender, Cinema 4D, and game engines like Unity. This makes it ideal for cross-platform asset sharing.
  • Technical Limitations:

    Due to its DOS-era origins, the format has strict constraints: mesh names are limited to 8 characters, and each mesh object can contain no more than 32,767 triangles. The format also lacks support for modern features like PBR materials or NURBS surfaces.

3DS File Converters

Our Autoconverter and Automesher Application automatically resolve legacy 3DS format constraints by intelligently partitioning large models into compliant, optimized sub-meshes. This ensures your 3D assets maintain integrity when exported to the 3DS format. While newer formats offer more features, 3DS remains valuable for legacy systems, lighting simulations, and situations requiring broad software support without complex dependencies.
