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.

In common CAD workflows, Parasolid transmit data is packaged in two extension sets—text forms like `.x_t` or `.xmt_txt` and binary forms like `.x_b` or `.xmt_bin`—where `.x_b` is now standard but `.xmt_bin` still appears, and to open it you import into a Parasolid-supporting CAD/CAE tool; if that tool lists just `.x_b`, renaming `. If you have any type of inquiries pertaining to where and the best ways to utilize XMT_BIN format, you can contact us at our own web site. xmt_bin` to `.x_b` usually lets it load successfully because both extensions point to the same binary Parasolid format.

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 other Parasolid CAD open it for inspection, dimensioning, drawing creation, and continued modeling, and also allowing CAE tools like ANSYS Workbench to use it for meshing and analysis.

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 for solid geometry or IGES surfaces 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 two main ways to open an `.xmt_bin` are using your CAD/CAE tool’s Parasolid import or renaming the file when the dialog filters extensions, with the import path selecting Parasolid from the file type options so the solid/surface model loads as intended, and the rename method changing `.xmt_bin` to `.x_b` so the software recognizes it as the same underlying Parasolid binary format.
