Convert PAR to PRT

Understanding PAR and PRT file formats

PAR files are 3D part files primarily associated with Siemens Solid Edge, a popular CAD software. These files store detailed 3D models, including geometry, features, and design parameters. PRT files, on the other hand, are part files used by several CAD programs, most notably PTC Creo and Siemens NX. They also contain 3D model data, but the format and structure differ depending on the originating software.

Why convert PAR to PRT?

Converting a PAR file to a PRT file is often necessary for collaboration between teams using different CAD platforms, or for migrating projects from Solid Edge to PTC Creo or Siemens NX. Direct conversion preserves 3D geometry and, in some cases, design features, making the transition smoother.

How to convert PAR to PRT

Direct conversion between PAR and PRT is not always straightforward due to proprietary formats. The most reliable method is to use an intermediate neutral format such as STEP (.stp, .step) or IGES (.igs, .iges), which are widely supported by most CAD software.

Recommended software for conversion

• Siemens Solid Edge: Open your PAR file, then use File → Save As → Save As Type and select STEP or IGES format.
• PTC Creo or Siemens NX: Import the STEP or IGES file using File → Open, then save as PRT using File → Save As.
• Autodesk Fusion 360: Supports importing and exporting both STEP and IGES files, making it a versatile intermediary.
• Online converters: Tools like Zamzar or AnyConv may support neutral format conversion, but for best results, use dedicated CAD software.

Step-by-step conversion process

1. Open the PAR file in Solid Edge.
2. Export the file as STEP or IGES via File → Save As → Save As Type.
3. Open the exported file in PTC Creo or Siemens NX.
4. Save the imported model as a PRT file using File → Save As.

Tips for successful conversion

• Always check the imported model for geometry errors or missing features.
• Use the latest versions of CAD software for improved compatibility.
• Consider using STEP format for better feature retention compared to IGES.

Conclusion

While there is no direct one-click solution for PAR to PRT conversion, using neutral formats like STEP or IGES with professional CAD software ensures the best results. Solid Edge and PTC Creo or Siemens NX are the recommended tools for this workflow.
