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.


DWG AutoCAD Drawing

Autodesk's AutoCAD is a leading software program in the field of Computer Aided Design (CAD). It is renowned for its support of the native DWG drawing format. Widely used by architects, engineers, and designers, AutoCAD enables precise 2D drafting and 3D modeling. Its powerful tools streamline the creation of technical drawings, floor plans, and construction documentation.

Key Features of AutoCAD

  • 2D Drafting & 3D Modeling:

    Create precise technical drawings and realistic 3D models with a comprehensive set of tools.
  • Customization & Automation:

    Use AutoLISP, scripts, and ObjectARX (AutoCAD’s advanced API) to build custom applications and automate workflows.
  • Native DWG Support:

    Work seamlessly with AutoCAD’s proprietary DWG format, ensuring optimal performance, compatibility, and data integrity.
  • Dynamic Blocks:

    Create intelligent, reusable blocks with adjustable properties.
