A `.XMT_BIN` file is most often 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: `. In case you beloved this article in addition to you desire to be given more details concerning XMT_BIN file description kindly check out the site. 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 `.x_b` usually works since importers read the binary Parasolid content regardless of the label.

With an `.xmt_bin` file, your primary workflow is leveraging its Parasolid solid/surface geometry by importing it into CAD for part review, measurement, drawing generation, or additional feature work in programs like other Parasolid-based CAD, and likewise loading it into CAE environments such as COMSOL Multiphysics for meshing and running analyses.

If you need to share the model with users who lack strong Parasolid support, you can convert it via your CAD system into broadly recognized formats such as generic STEP for solids or 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.
