Exporting SOLIDWORKS files as 3MF Files

You can export SOLIDWORKS part and assembly files as 3MF files.

To export SOLIDWORKS files as 3MF files:

  1. With a model open, click Save As (Standard toolbar) or File > Save As.
  2. In the dialog box:
    1. Set Save as type to 3D Manufacturing Format (*.3mf).
    2. Click Options.
  3. In the dialog box, set these options:
    Option Description
    File Format Displays the selected file format.
    Output as

    For Unit, select the unit of measure.

    Resolution Controls the tessellation of non-planar surfaces for 3MF output. A lower deviation setting produces a more-finely-tessellated 3MF file. Files generated with higher accuracy settings (increased tessellation) are larger in size and slower to generate.

    Coarse or Fine

    Preset resolutions.

    Custom

    • Move the Deviation slider to adjust the deviation Tolerance, which controls whole-part tessellation. Lower numbers generate files with greater whole-part accuracy.
    • Move the Angle slider to adjust the angle Tolerance, which controls small-detail tessellation. Lower numbers generate files with greater small-detail accuracy, but those files take longer to generate.
    As you move the two sliders, the corresponding concentric circles adjust accordingly. The circles show approximately how the tessellation will vary as a result of the settings. (See Preview below.)

    Show 3MF info before saving file

    Displays this information: Triangles (number), File Size, File Format, and the directory path and file name.

    Preview before saving file

    Displays a faceted model preview and displays the Triangles (number) and File size information in the System Options dialog box.

    Include materials Includes base materials with the exported file.
    Include appearences Includes appearances with the exported file. Only surface-mapped textural appearances are exported to 3MF.
    Output coordinate system Select a coordinate system to apply for export. If you select -- default --, no transformation matrix is applied.
  4. Click OK.
  5. Click Save.
