A `.XMT_BIN` file is largely associated with a Parasolid "binary transmit" exchange file that embeds the actual model geometry—faces, edges, solids—straight from the Parasolid kernel, helping CAD tools swap accurate data through a serialized binary form that’s optimized for performance and not human-readable.
Functionally, Parasolid transmit files come in text (`.x_t`, `.xmt_txt`) and binary (`.x_b`, `.

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 Siemens NX, and likewise load it into CAE tools such as COMSOL Multiphysics for meshing and simulation.
If the recipient’s software doesn’t support Parasolid properly, you can export to more universal types like STEP AP214 for high-quality solids or IGES surfaces when surfaces dominate, or switch to mesh formats like OBJ for printing/visual use while accepting the loss of analytic geometry; you can also import the file for healing/stitching repairs before re-export, and `.xmt_bin` versions help troubleshoot by revealing whether problems stem from the native CAD model or occur only during translation.
The easiest methods to access an `.xmt_bin` file are importing it straight into a Parasolid-compatible CAD/CAE tool or renaming it when the software only recognizes `.x_b`, where the direct import path uses File → Open/Import with Parasolid selected so the translator loads the solid/surface data, while the rename trick works because `.xmt_bin` and `.x_b` represent the same binary Parasolid transmit type and the altered name merely satisfies the file filter.
