A `.XMT_BIN` file is usually a Parasolid binary transmit file, meaning it’s a compact non-readable 3D exchange format that stores the actual solid and surface geometry from the Parasolid kernel rather than drawings or meshes, effectively passing the true model structure between Parasolid-based tools in a fast serialized binary snapshot that isn’t viewable in a text editor.
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 `.

With an `.xmt_bin` file, the primary purpose is to import the Parasolid solid/surface model it contains into other engineering environments, allowing CAD users to inspect geometry, measure, create drawings, or build further features in systems like compatible Parasolid tools, and similarly send the geometry into CAE platforms such as other analysis software for meshing and simulation steps.
If Parasolid isn’t well supported on the receiving end—because their tool has weak Parasolid import—you can export to universal formats such as STEP AP242 for solid geometry or IGES surfaces for surface-heavy models, or to mesh types like OBJ 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 `.x_b` so programs that hide `.xmt_bin` still accept it as the same binary Parasolid format.
