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.

3MF 3D Manufacturing File

An open-source XML file format developed by the 3MF Consortium, a collaboration of companies and organizations in the 3D printing industry. It was designed to overcome the limitations of older formats, such as STL, which only store geometric data, by providing a more comprehensive and extensible framework for additive manufacturing workflows.

Main Advantages Over STL

Unlike STL, 3MF can store additional information, making it a more advanced and versatile choice for additive manufacturing:

  • Color Support:

    Defines the color of individual triangles, enabling more realistic and visually detailed prints.

  • Transparency:

    Specifies opacity levels for triangles or vertices, allowing for the creation of transparent or translucent objects.

  • Textures:

    Supports texture mapping by associating 2D images with 3D models, enhancing realism in prints.

  • Metadata:

    Allows embedding custom data such as author, title, description, and license, facilitating better file management and sharing.

3MF File Conversion

Our products, Autoconverter and Automesher Application, are fully compatible with the 3MF file format. They utilize the official lib3mf library to enable seamless import and export of 3MF files. A significant limitation of the 3MF format is its lack of support for group hierarchies. When converting a 3D model containing nested subgroups - often used for organizational purposes - these structural relationships are not preserved in the 3MF file. Despite this, 3MF remains a powerful and modern format for 3D printing, offering a rich set of features that go beyond traditional STL files.
