A `.XMT_BIN` file is primarily used as 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 practice, Parasolid transmit files usually come in two interchangeable extension sets: text forms like `.x_t` or `.xmt_txt` and binary forms like `.x_b` or `.xmt_bin`, with `.x_b` being more common today while `.xmt_bin` survives as an alternate naming, and to open one you normally import it into a Parasolid-compatible CAD/CAE tool—renaming `.xmt_bin` to `.x_b` often works when the importer only lists `.x_b` even though both represent the same binary Parasolid idea.

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 Parasolid-supporting CAD, while also allowing import into simulation tools like other CAE systems for meshing and physics analysis.

If the recipient’s software has limited Parasolid capability, you can export to more universal types like STEP AP214 for high-quality solids or IGES when surfaces dominate, or switch to mesh formats like STL for printing/visual use while accepting the loss of analytic geometry; you can also import the file for healing/stitching repairs before re-export, and `.

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 `.x_b`, letting the importer accept it since both extensions represent binary Parasolid transmit data.
