A `.XMT_BIN` file is usually 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 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 `.

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 SOLIDWORKS, and similarly send the geometry into CAE platforms such as other analysis software for meshing and simulation steps.
If your goal is sharing with someone whose software doesn’t handle Parasolid well, you can convert the file through your CAD exporter or a translator into formats like ISO STEP for solid accuracy or IGES surface data for older surface workflows, or into mesh formats like STL/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 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.
