Convert PRT to another file type
To convert PRT parts to another format, you need Siemens NX or other Cad software.
Convert a file to PRT
To convert other file formats to the "3D Part Model" file type, you need software like Siemens NX or a similar tool.
About PRT files
The .PRT file extension is primarily used for 3D CAD part files created by high-end engineering platforms like Siemens NX and PTC Creo. These files store intricate 3D model geometry, part structures, and manufacturing metadata. The major disadvantage of the .PRT format is severe ecosystem lock-in. It is heavily proprietary, meaning a .PRT file generated by Siemens NX cannot be natively opened by PTC Creo without specialized, expensive translation plugins. Working with these files typically requires gigabytes of software installation and enterprise licenses that cost thousands of dollars per seat. Version incompatibility is also a chronic real-world problem; older software versions frequently fail to open .PRT files saved by newer updates. To collaborate with manufacturers, clients, or engineers outside your specific software ecosystem, you must convert the file to a standard neutral format. Drag and drop your file here to analyze and convert it - free, online, and without installing software. For universal cross-platform CAD editing and manufacturing, convert to .STEP or .IGES. For rapid 3D printing or basic visualization on the web, convert to .STL or .OBJ. Be aware that converting a feature-rich .PRT file to a mesh format like .STL will permanently discard the parametric design history and feature tree, leaving only the external geometry.
Convert.Guru analyzes your PRT file, detects the exact format, and lets you read the text inside.
If you want to convert PRT file to PDF, STEP, STL, STP, DWG, DXF, SLDPRT, DGN, RVT, RFA, SKP or 3DM, you can use Siemens NX or similar software from the "3D CAD Part Model" category. In the File menu, look for Save As… or Export….
To convert SLDASM, DGN, IAM, X_B, CATPRODUCT, SLDPRT, RVT, ASM, DWG, CATPART, DXF or X_T files to PRT, try Siemens NX or another comparable tool in the "3D CAD Part Model" category.
The PRT 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 PRT converter.
