A `.XMT_BIN` file is most commonly interpreted as a Parasolid binary transmit object containing solid and surface geometry directly from the Parasolid kernel, enabling cleaner transfers between Parasolid-based CAD systems by packaging the true model definition into a compact binary exchange file that can’t be understood in a text editor.

Functionally, Parasolid transmit files come in text (`.x_t`, `.xmt_txt`) and binary (`.x_b`, `.xmt_bin`) flavor pairs that most systems treat as equivalents, with `.x_b` more common and `.xmt_bin` used by some exporters, and accessing the file means importing it into Parasolid-compatible software; when the importer displays only `.x_b`, renaming `.xmt_bin` to `.x_b` is a common workaround since the binary content itself doesn’t change.

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 Siemens NX open it for inspection, dimensioning, drawing creation, and continued modeling, and also allowing CAE tools like other simulators to use it for meshing and analysis.

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 mesh-based formats 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.

Opening an `.xmt_bin` generally means either importing it directly through a Parasolid-capable program or renaming it for tools that only list `.
