A `.XMT_BIN` file is most widely known as a Parasolid "binary transmit" format, which holds real model geometry and topology in the Parasolid kernel’s exchange form instead of mesh or drawing data, allowing CAD programs that use Parasolid to share accurate geometry through a binary snapshot optimized for speed and unreadable as plain text.

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 `.

With an `.xmt_bin` file, you’re mainly working with high-fidelity Parasolid solid and surface geometry rather than drawings or meshes, meaning you can import it into CAD to inspect the model, verify dimensions, produce drawings, or continue feature-based modeling in Parasolid-friendly tools like SOLIDWORKS, and you can also feed it into CAE platforms such as COMSOL Multiphysics for meshing and analysis.

If you need to share the model with users who can’t open Parasolid reliably, you can convert it via your CAD system into broadly recognized formats such as generic STEP for solids or legacy IGES for surface-heavy data, or into mesh types like STL/OBJ for printing or visualization at the cost of losing real CAD geometry; you can also clean the model by importing it, using heal/repair tools, and exporting again, and you can use the `.xmt_bin` as a diagnostic export to test whether issues come from the native model or from translation when reimported elsewhere.

You can open an `.xmt_bin` file by importing it directly as Parasolid inside supported CAD/CAE software or by renaming it when the file dialog won’t show `.xmt_bin`, where the first method involves choosing Parasolid from the file type list so the importer brings in the model, and the second method renames the file to `.x_b`, letting the tool read it because both extensions correspond to binary Parasolid transmit files.
