A `.XMT_BIN` file is usually meant to be a Parasolid "binary transmit" container, which transports the authentic model geometry from the Parasolid kernel rather than mesh or drawing data, producing a fast, size-efficient binary snapshot for CAD interoperability that isn’t interpretable in a normal text editor.

In everyday use, Parasolid transmit formats appear in two main extension groups—text (`.x_t`, `.xmt_txt`) and binary (`.x_b`, `.xmt_bin`)—with `.x_b` being today’s standard and `.xmt_bin` remaining an alternate tag, and you open such files by importing them into a CAD/CAE tool that supports Parasolid; if it only filters `.x_b`, renaming `.xmt_bin` to `.x_b` generally allows the program to load it because the internal structure is the same.

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 SOLIDWORKS open it for inspection, dimensioning, drawing creation, and continued modeling, and also allowing CAE tools like COMSOL Multiphysics to use it for meshing and analysis.

If you have any concerns with regards to where and how to use XMT_BIN file compatibility, you can get hold of us at our page. If you’re sharing with someone whose program lacks Parasolid compatibility, you can convert to widely supported standards such as STEP for solids or IGES surfaces for surface geometry, or to mesh options like OBJ for printing or visualization—though meshes sacrifice CAD-level intelligence; you can also use the import process to run heal/repair features before exporting a cleaner file, and an `.xmt_bin` export can help diagnose whether issues come from original modeling or translation inconsistencies.

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.
