How to open a .parasolid (x_t, x_b) file
Start with a trusted app that supports this format
- Check the file extension carefully and confirm that the file name really ends with .parasolid (x_t, x_b).
- Use software that supports this file type. If one app does not work, try another compatible program for the same platform.
- Update the application if the file was created by a newer version of the software.
- Scan files from unknown sources before opening them, especially documents, archives, scripts, installers, and executable files.
What is a .parasolid (x_t, x_b) file?
File extension details and usage information
Parasolid files, typically with extensions like .x_t (text) or .x_b (binary), are a common format for representing 3D solid models. They are the native file format for the Parasolid geometric modeling kernel, a widely used kernel in various CAD/CAM/CAE software applications. These files store the geometric and topological information of a 3D object, including its surfaces, edges, vertices, and relationships between them. The .x_t format is a human-readable ASCII text format, making it easier to inspect and potentially edit (though not recommended for complex models). The .x_b format is a binary format, which is more compact and efficient for storage and transfer of large models. Parasolid files are often used for exchanging 3D model data between different CAD systems, as the Parasolid kernel is licensed to many software vendors. They are crucial for interoperability in the product development process, allowing engineers and designers to share and collaborate on 3D models regardless of the specific CAD software they use. The files contain precise geometric data, enabling accurate simulations, manufacturing processes, and visualization.

Can .parasolid (x_t, x_b) files be converted?
Options for saving or exporting this file to another format
In many cases, a .parasolid (x_t, x_b) file can be converted by opening it in compatible software and using an option such as Save As, Export, or Convert. The available output formats depend on the file type and the application used.
- Use the original software that created the file when possible.
- Check whether the application supports exporting to common formats.
- Be careful with online converters when working with private, business, or sensitive files.
- If conversion fails, the file may be corrupted, incomplete, encrypted, or not actually a .parasolid (x_t, x_b) file.
Why can't I open a .parasolid (x_t, x_b) file?
Common reasons this file type may not open correctly
Wrong software
The file may require a specific program that supports the .parasolid (x_t, x_b) format.
Incorrect extension
The file extension may have been renamed manually, even though the actual file format is different.
Corrupted file
The file may be incomplete, damaged during download, or transferred incorrectly.
Outdated app
Your software may need to be updated before it can open newer versions of this file format.
Frequently Asked Questions
Common questions about .parasolid (x_t, x_b) files
To open a .parasolid (x_t, x_b) file, use software that supports this file format.
- Siemens NX
- Solid Edge
- SOLIDWORKS
- Autodesk Inventor
- Autodesk Fusion 360
Open the file in compatible software and look for options such as Save As, Export, or Convert. If no export option is available, the file may require a specialized converter or the original application that created it.
- Verify that the file extension is correct.
- Install or update compatible software.
- Try another application that supports this format.
- Check whether the file is corrupted, incomplete, or encrypted.
A file extension alone does not guarantee whether a file is safe or unsafe. Only open files from trusted sources, scan unknown files before opening them, and be especially careful with executable, script, archive, and document files.
File safety tips
Use caution with unknown files
Only open files from trusted sources. Before opening a .parasolid (x_t, x_b) file, scan it with antivirus software, verify that the file extension is expected, and avoid running unknown executable, installer, macro-enabled document, or script files.
