A `.XMT_BIN` file is primarily used as 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.

In real workflows, Parasolid transmit data appears through two extension families: text versions such as `.x_t` or `.xmt_txt` and binary versions like `.x_b` or `.xmt_bin`, where `.x_b` tends to dominate while `.xmt_bin` is kept by some exporters, and opening one simply means bringing it into a Parasolid-aware CAD/CAE app—if the app filters only `.x_b`, renaming from `.xmt_bin` to `.

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 other Parasolid CAD programs, and likewise load it into CAE tools such as similar simulators for meshing and simulation.

If Parasolid isn’t well supported on the receiving end—because their tool can’t read Parasolid well—you can export to universal formats such as STEP AP214 for solid geometry or legacy IGES routes for surface-heavy models, or to mesh types like STL 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 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.
