A `.XMT_BIN` file typically represents 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.

Practically speaking, Parasolid transmit files show up as two extension pairs: `.x_t`/`.xmt_txt` for text and `.x_b`/`.xmt_bin` for binary, with `.x_b` now the more frequent choice although `.xmt_bin` still circulates, and opening the file involves importing it into software that understands Parasolid; when only `.x_b` is listed, copying and renaming `.xmt_bin` to `.x_b` usually works since importers read the binary Parasolid content regardless of the label.

With an `.xmt_bin` file, what you mainly do is import its Parasolid geometry into engineering software, since it stores full solid/surface data rather than meshes or drawings, letting CAD systems such as Siemens NX open it for inspection, dimensioning, drawing creation, and continued modeling, and also allowing CAE tools like other simulators to use it for meshing and analysis.

If Parasolid isn’t well supported on the receiving end—because their tool doesn’t fully support Parasolid—you can export to universal formats such as STEP AP242 for solid geometry or IGES for surface-heavy models, or to mesh types like STL when needed, understanding that meshes lose true CAD fidelity; you can also import the geometry to run healing/repair operations before re-exporting, and an `.xmt_bin` is useful diagnostically to test whether issues persist after translation, helping pinpoint modeling vs. conversion faults.

The two simplest ways to open an `.xmt_bin` file are either importing it directly as a Parasolid file in software that already supports Parasolid or renaming it to a more commonly accepted Parasolid-binary extension when the file picker is being strict, with the first method using File → Open/Import and selecting Parasolid to load the solid/surface model properly, and the second method involving copying and renaming the file to `.
