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.


X Direct3D File

Developed by Microsoft in 1995 as part of DirectX for Windows 95, this format stores 3D mesh geometry along with materials and textures. It served as the original interchange format for DirectX’s graphics and multimedia APIs.

Key Features of X

  • Origin: Developed by Microsoft in 1995 as part of DirectX.
  • Geometry: Stores 3D mesh data including vertices, faces, and normals.
  • Animation: Supports skeletal animation with bone hierarchies and skinning weights.
  • UV Mapping: Includes texture coordinate data for applied images.

X File Conversion

Autoconverter and Automesher Application enable effortless conversion of X files to your native 3D environment, including STL, OBJ, 3DM, SKP, STEP, and other industry-standard formats to bridge DirectX assets with CAD, 3D printing, and computational design workflows. Need to modernize legacy X files? Our X file converters ensure smooth transitions to contemporary workflows.
