3DM Rhinoceros 3D File

The native file format for Rhinoceros 3D (Rhino), a powerful and versatile NURBS-based 3D modeling software. As Rhino’s default format, 3DM is designed to store precise mathematical representations of curves, surfaces, and solids, making it ideal for high-accuracy modeling across industries.

Supported Geometry Types

Known for its precision and versatility, the 3DM format supports a comprehensive range of geometric data types, making it ideal for both organic freeform modeling and technical CAD applications, including:

  • NURBS Surfaces:

    Enables mathematically precise, smooth, and editable surfaces essential for high-end industrial and automotive design.

  • Polygonal Meshes:

    Stores tessellated geometry for 3D printing, rendering, and simulation.

  • SubD (Subdivision Surfaces):

    Allows for flexible, organic modeling with editable subdivision geometry.

  • Instance References:

    Lightweight object copies (not duplicates) that reference a single source, saving memory and ensuring synchronized updates.

3DM File Conversion

Our software solutions enable seamless conversion between 3DM and other major CAD formats (e.g., STEP, IGES, OBJ, DWG, STL). Autoconverter exports only polygonal meshes (STL, OBJ, etc.), suitable for 3D printing and real-time rendering, while Autoshaper preserves NURBS geometry, ensuring superior accuracy for CAD, CAM, and engineering workflows. Both converters can save 3DM files in legacy formats (Rhino 2.X - 7.X) or the latest Rhino 8.X version, ensuring smooth collaboration across different software environments.

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.
