A `.XMT_BIN` file is best described as a Parasolid "binary transmit" container, which transports the authentic model geometry from the Parasolid kernel rather than mesh or drawing data, producing a fast, size-efficient binary snapshot for CAD interoperability that isn’t interpretable in a normal text editor.
In everyday use, Parasolid transmit formats appear in two main extension groups—text (`.x_t`, `. Here is more info on

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 other Parasolid CAD open it for inspection, dimensioning, drawing creation, and continued modeling, and also allowing CAE tools like ANSYS Workbench to use it for meshing and analysis.
If you’re sending the model to someone whose software handles Parasolid poorly, the fix is converting to formats like STEP for solid fidelity or IGES legacy 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.
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.
