A `.XMT_BIN` file is most widely known as a Parasolid “binary transmit” format, which holds real model geometry and topology in the Parasolid kernel’s exchange form instead of mesh or drawing data, allowing CAD programs that use Parasolid to share accurate geometry through a binary snapshot optimized for speed and unreadable as plain text.
In everyday use, Parasolid transmit formats appear in two main extension groups—text (`.

With an `.xmt_bin` file, the key use is bringing its Parasolid solid/surface data into engineering software, since it holds real model geometry instead of mesh or drawing information, letting you open it in CAD to review shapes, measure, generate drawings, or keep modeling inside apps like SOLIDWORKS, and likewise load it into CAE tools such as ANSYS Workbench for meshing and simulation.
If you’re sending the model to someone whose software handles Parasolid poorly, the fix is converting to formats like STEP AP242 for solid fidelity or IGES for surface workflows, or to mesh types like standard mesh exports for printing/visualization while accepting the loss of analytic CAD surfaces; you can also heal or stitch geometry in the receiving tool before exporting again, and using an `.xmt_bin` export is a common troubleshooting step to see whether problems originate from your native CAD model or appear only during file translation.
To open an `.xmt_bin`, you can either import it as a Parasolid file in a tool that supports Parasolid or rename it if the program only displays `.x_b`, with the import route using File → Open/Import under the Parasolid file type so the geometry loads correctly, and the rename route copying `file.xmt_bin` to `file.x_b` so the UI accepts it even though both extensions map to the same binary Parasolid transmit data.
