Parasolid Files (*.x_t, *.x_b)

  • Data exported to or imported from Parasolid format retains its color when displayed in Shaded mode.
  • Component names in assemblies are retained for both import and export.
  • The Parasolid translator does not support the import or export of point data.
  • The Parasolid translator supports import and export of curves and wireframes.


  • The Parasolid translator imports Parasolid text files or binary files as SOLIDWORKS documents.
  • The Parasolid translator imports files with the extension .x_t, .x_b, .xmt_txt, or .xmt_bin.


The Parasolid translator exports SOLIDWORKS part or assembly documents as Parasolid text files or binary files. Binary files are smaller than text files, but binary files are not supported in some target applications.

If you export a SOLIDWORKS assembly document that has hidden or suppressed components to a Parasolid text or binary file, a dialog box appears asking if you want to resolve these components.

The Parasolid translator includes export options.

Parasolid Export Options

You can set the export options when you export SOLIDWORKS part or assembly documents as Parasolid files.

To set the Parasolid export options:

  1. Open the SOLIDWORKS document that you want to export as a Parasolid file.
  2. Click File > Save As.
  3. Optional: 3DEXPERIENCE Users: If the Save As New dialog box appears, click Save to This PC.
  4. Set Save as type to Parasolid (*.x_t) or Parasolid Binary (*.x_b), then click Options.
    The Export Options dialog box appears with Parasolid selected on the File Format tab.
  5. Select from the following options:
    Option Description
    Version Select the type supported by the target system.
    Flatten assembly hierarchy (assemblies only) Flattens the assembly to one level of only part bodies. A flattened file contains a top-level assembly and a series of parts that contain imported features.
    Output coordinate system Select a coordinate system to apply for export. If you select -- default --, no transformation matrix is applied.
  6. Click OK, then click Save to export the document.
