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 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 primary purpose is to import the Parasolid solid/surface model it contains into other engineering environments, allowing CAD users to inspect geometry, measure, create drawings, or build further features in systems like compatible Parasolid tools, and similarly send the geometry into CAE platforms such as COMSOL Multiphysics for meshing and simulation steps.
If your goal is sharing with someone whose software can’t reliably read Parasolid, you can convert the file through your CAD exporter or a translator into formats like ISO STEP for solid accuracy or IGES for older surface workflows, or into mesh formats like OBJ when 3D printing or visualization is required—keeping in mind that meshes lose true CAD surfaces and features; you can also import the file to run heal/stitch/repair tools before re-exporting a cleaner model, and as a diagnostic step you can export to Parasolid to see whether issues persist on import elsewhere, helping distinguish modeling problems from translation problems.
The easiest methods to access an `.xmt_bin` file are importing it straight into a Parasolid-compatible CAD/CAE tool or renaming it when the software only recognizes `.x_b`, where the direct import path uses File → Open/Import with Parasolid selected so the translator loads the solid/surface data, while the rename trick works because `.xmt_bin` and `.
