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.
In practice, Parasolid transmit files usually come in two interchangeable extension sets: text forms like `.x_t` or `.xmt_txt` and binary forms like `.x_b` or `.xmt_bin`, with `.x_b` being more common today while `.xmt_bin` survives as an alternate naming, and to open one you normally import it into a Parasolid-compatible CAD/CAE tool—renaming `.xmt_bin` to `.x_b` often works when the importer only lists `.x_b` even though both represent the same binary Parasolid idea.
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 SOLIDWORKS open it for inspection, dimensioning, drawing creation, and continued modeling, and also allowing CAE tools like COMSOL Multiphysics to use it for meshing and analysis.
If you’re sending the model to someone whose software cannot process Parasolid files well, the fix is converting to formats like STEP solids for solid fidelity or IGES legacy for surface workflows, or to mesh types like STL 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.
