X_T to TXT Converter

X_T to TXT Conversion Explained

Converting .X_T (Parasolid Text Transmit) to .TXT (Plain Text) changes a 3D CAD model into a standard text document. Because .X_T is already an ASCII-based format, its raw data is technically text. However, a true conversion usually involves extracting specific information—such as metadata, Bill of Materials (BOM), or XYZ coordinate points—and formatting it into a readable .TXT file.

People convert .X_T to .TXT to extract data without needing expensive CAD software. You gain universal readability, easy text searching, and the ability to process the data with simple scripts. You lose all 3D visualization, geometric rendering, and the ability to edit the file as a solid model. If your goal is to view or modify 3D geometry, this conversion is a bad idea.

Typical Tasks and Users

This conversion serves highly specific technical workflows rather than general design tasks:

• Software Developers: Writing custom parsers to read Parasolid boundary representation (B-rep) data and outputting specific node structures to a text log for debugging.
• Data Analysts: Extracting part names, assembly hierarchies, or metadata from CAD files to populate databases or spreadsheets.
• CNC Programmers: Pulling raw XYZ coordinate data from a 3D model to feed into legacy machining systems that only accept plain text inputs.
• Version Control Managers: Converting CAD data into structured text to track changes (diffs) in Git or Subversion repositories.

Software & Tool Support

Handling .X_T files usually requires specialized engineering software, while .TXT is universally supported.

• CAD Software: .X_T is the native kernel format for Siemens Digital Industries Software. It is natively exported and opened by SolidWorks, Siemens NX, and Onshape. These tools can often export BOMs or coordinate reports as .TXT.
• Text Editors: Because .X_T is ASCII, you can open it directly in Notepad++ or Visual Studio Code to view the raw schema, though the data will look like a dense wall of numbers and node references.
• Programming Libraries: Developers use Python or C++ alongside the official Parasolid Communicator to parse .X_T files and write specific data to .TXT.

Pros and Cons of the Conversion

Pros:

• Universal Compatibility: Every operating system and device can open a .TXT file instantly.
• Searchability: You can easily use grep, regex, or basic search functions to find specific part numbers or coordinates.
• Scripting: Plain text is the easiest format to feed into custom Python, Bash, or PowerShell scripts.
• File Size: If you extract only metadata or specific coordinates, the resulting .TXT file is significantly smaller than the original CAD model.

Cons:

• Total Loss of 3D Data: A .TXT file cannot be opened in a 3D viewer or CAD program to see the physical model.
• Complex Parsing: Raw .X_T data uses a strict, proprietary schema. Without proper extraction, the text is unreadable to humans.
• One-Way Process: You cannot convert an extracted .TXT report back into a working .X_T 3D model.

Conversion Difficulties & Why Convert.Guru

The main technical difficulty in converting .X_T to .TXT is parsing the Parasolid schema. An .X_T file contains a sequential list of topological nodes (faces, edges, vertices) and geometric definitions (NURBS curves, surfaces). Simply renaming the file extension from .X_T to .TXT exposes this raw data, but it does not make it useful. To get a meaningful text file, the conversion pipeline must read the proprietary schema, identify the requested data (like assembly structure or bounding box coordinates), strip away the complex B-rep math, and format the output cleanly.

Convert.Guru handles this extraction accurately. Instead of just renaming the file, Convert.Guru processes the underlying Parasolid structure to extract readable metadata and structural summaries. It provides a clean, formatted .TXT file without requiring you to install heavy CAD software or write custom parsing scripts.

X_T vs. TXT: What is the better choice?

Which format should you choose?

Choose .X_T when you need to store, edit, or share 3D solid models between different engineering teams. It is the industry standard for moving precise geometric data between CAD systems.

Choose .TXT only when you need to extract specific text-based data—such as part lists, metadata, or coordinate points—for use in databases, legacy systems, or custom scripts.

Avoid this conversion entirely if you are trying to send a 3D model to a manufacturer or a client who does not have SolidWorks. Instead of converting to .TXT, convert your .X_T file to .STEP or .IGES, which are universally accepted 3D formats.

Conclusion

Converting .X_T to .TXT is a specialized data extraction process, not a visual conversion. It makes sense when you need to pull metadata, BOMs, or coordinates out of a CAD model for scripting, database entry, or version control. The biggest limitation is the complete destruction of 3D visual data; the resulting file cannot be used for design or manufacturing. Convert.Guru offers a reliable, fast way to extract this text data from complex Parasolid files, ensuring you get clean, usable information without needing expensive engineering software.
