OFF to STEP Conversion

Our step-by-step tutorial makes converting OFF to STEP quick and effortless:

  1. Download & Install:

    Convert your OFF files to STEP format seamlessly using our Autoconverter or Autoshaper - simply install and launch the software on your system.
  2. Import OFF File:

    Either click Open... to browse for your .off file, or drag and drop it anywhere in the application window.
  3. Export to STEP Format:

    Use Save As... to specify both location and filename (with .step extension) for your exported file.

OFF 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.


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.
