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.

Functionally, Parasolid transmit files come in text (`.

With an `.xmt_bin` file, the essential action is loading its Parasolid-based solid and surface geometry into CAD or CAE applications, enabling you to examine the part, check measurements, generate drawings, or extend modeling inside SOLIDWORKS, while also allowing import into simulation tools like ANSYS Workbench for meshing and physics analysis.

If you need to share the model with users who lack strong Parasolid support, you can convert it via your CAD system into broadly recognized formats such as STEP AP242 for solids or IGES for surface-heavy data, or into mesh types like STL/OBJ for printing or visualization at the cost of losing real CAD geometry; you can also clean the model by importing it, using heal/repair tools, and exporting again, and you can use the `.xmt_bin` as a diagnostic export to test whether issues come from the native model or from translation when reimported elsewhere.

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 `.x_b` so programs that hide `.xmt_bin` still accept it as the same binary Parasolid format.
