Convert JT to another file type
To convert JT 3D files to another format, you need Siemens JT2Go or other 3D software.
Convert a file to JT
To convert other file formats to the "3D CAD Visualization File" file type, you need software like Siemens JT2Go or a similar tool.
About JT files
The .JT (Jupiter Tessellation) file is primarily a lightweight 3D product visualization format developed by Siemens Digital Industries Software. It is heavily used in enterprise Product Lifecycle Management (PLM) to share 3D models without distributing heavy, proprietary CAD files. These files contain polygonal mesh data, Boundary Representation (B-rep), and Product and Manufacturing Information (PMI). A rare secondary use for the .JT extension is a plain-text JSON configuration file for the CoolLED1248 mobile app.
.JT files are specialized for industrial workflows. The main disadvantage is that consumer-grade 3D viewers and 3D printing software cannot read them. They often require expensive enterprise software or specialized free viewers like Siemens JT2Go to access the underlying B-rep or PMI data. Users outside of the original engineering team will struggle to open or interact with these files.
To use these models in common applications, you must convert them. The best target formats are STEP or IGES for generic CAD editing, or STL and OBJ for 3D printing and rendering. Note that converting a .JT to STL will strip out all precision B-rep data and metadata, leaving only the polygonal mesh.
Because .JT is a highly complex engineering format, converting B-rep data accurately often requires the original CAD engine. Standard online converters frequently fail to parse the intricate geometry. If our analysis detects the secondary plain-text JSON variant or an extractable embedded mesh format, viewing or conversion may still be possible.
Convert.Guru analyzes your JT file, detects the exact format, and lets you read the text inside.
If you want to convert JT file to STEP, DXF, DWG, DGN, RVT, RFA, SKP, 3DM, IGES, SAT, X_T or X_B, you can use Siemens JT2Go or similar software from the "3D Product Visualization" category. In the File menu, look for Save As… or Export….
To convert SLDASM, DGN, PRT, IAM, X_B, CATPRODUCT, SLDPRT, RVT, ASM, DWG, CATPART or DXF files to JT, try Siemens JT2Go or another comparable tool in the "3D Product Visualization" category.
The JT Converter Story
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 JT converter.
