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.

In real workflows, Parasolid transmit data appears through two extension families: text versions such as `.x_t` or `.xmt_txt` and binary versions like `.x_b` or `.xmt_bin`, where `.x_b` tends to dominate while `.xmt_bin` is kept by some exporters, and opening one simply means bringing it into a Parasolid-aware CAD/CAE app—if the app filters only `.x_b`, renaming from `.xmt_bin` to `.x_b` typically succeeds because the format underneath is identical.

With an `.xmt_bin` file, the essential action is loading its Parasolid-based solid and surface geometry into CAD or CAE applications, enabling you to examine the part, check measurements, generate drawings, or extend modeling inside SOLIDWORKS, while also allowing import into simulation tools like other CAE systems for meshing and physics analysis.

If you’re sharing with someone whose program struggles with Parasolid, you can convert to widely supported standards such as STEP AP242 for solids or IGES 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.

Opening an `.xmt_bin` generally means either importing it directly through a Parasolid-capable program or renaming it for tools that only list `.x_b`, as the direct method relies on choosing Parasolid in File → Open/Import to bring in the geometry cleanly, while the rename approach works by copying and renaming the file to `.
