Extract text from Parasolid CAD models (XMT_TXT)
To convert XMT_TXT CAD models to another format, you need Siemens NX or other Cad software.
To convert other file formats to the "3D Modeling Geometry" file type, you need software like Siemens NX or a similar tool.
The .xmt_txt file is a text-based 3D CAD model generated by the Parasolid geometric modeling kernel. Engineers and product designers use it to exchange precise 3D boundary representation (B-rep) geometry between different manufacturing and CAD systems.
It is primarily opened, edited, and exported using professional engineering tools like Siemens NX and SolidWorks. You can read more about the underlying geometric kernel on its Wikipedia page.
The .xmt_txt format is a highly specialized engineering file with significant practical limitations. It requires an expensive, active CAD subscription to open and evaluate. Because it stores complex 3D mathematics in plain text, files frequently exceed 100MB and are completely unreadable by standard web browsers, document viewers, or mobile devices. Sharing these files directly with non-technical clients or external partners usually results in them being unable to view the design.
To solve this, you must convert .xmt_txt into universal 3D formats. Target STEP or IGES for engineering collaboration, as these retain the exact mathematical curves. Target STL or OBJ for 3D printing and quick rendering. Be aware that converting to STL destroys the precise curved geometry and replaces it with a flat, faceted mesh, meaning it can no longer be easily edited in CAD software.
This closed, proprietary format is exceptionally difficult to open or convert online. Standard file converters fail to process it because translating B-rep mathematics requires an expensive, licensed CAD engine. Often, only the original software can properly read or export the data. However, you can drag and drop your file onto convert.guru to identify the format, inspect the internal text structure, and show readable text. If our analysis detects a supported underlying or embedded 3D format, viewing or conversion may still be possible.
Convert.Guru analyzes your XMT_TXT file, detects the exact format, and lets you read the text inside.
Users also converted XMT, X_T, X_B and PNX files.
If you want to convert XMT_TXT file to , you can use Siemens NX or similar software from the "3D CAD Data Exchange" category. In the File menu, look for Save As… or Export….
To convert files to XMT_TXT, try Siemens NX or another comparable tool in the "3D CAD Data Exchange" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our XMT_TXT converter.
