Convert IGS to PAR

Understanding IGES (.igs) and PAR (.par) file formats

IGES (.igs) is a widely used neutral file format for exchanging 2D and 3D CAD data between different CAD systems. It stands for Initial Graphics Exchange Specification and is commonly used for transferring wireframe, surface, and solid models.

PAR (.par) is the native part file format for Siemens Solid Edge, a popular 3D CAD software. PAR files store parametric part models, including features, sketches, and design history, making them essential for further editing and design within Solid Edge.

Why convert IGES to PAR?

Converting an IGES file to a PAR file allows you to import generic CAD data into Solid Edge for advanced editing, parametric modeling, and integration into assemblies. This is especially useful when collaborating with partners using different CAD platforms.

How to convert IGES (.igs) to PAR (.par)

The most reliable way to convert IGES files to PAR format is by using Siemens Solid Edge itself, as it natively supports both formats. Here’s how you can do it:

1. Open Solid Edge.
2. Go to File → Open and select your .igs file.
3. Solid Edge will import the IGES file. You may need to use the Import Options to adjust settings for surfaces, solids, or units.
4. Once the file is imported, review and repair any geometry if necessary using Solid Edge’s repair tools.
5. Save the imported model as a .par file by selecting File → Save As and choosing PAR (*.par) as the file type.

Recommended software for IGES to PAR conversion

• Siemens Solid Edge – The best and most accurate tool for this conversion, ensuring full compatibility and editability.
• Autodesk Inventor or PTC Creo – These can import IGES files and export to other formats, but direct PAR export is not supported. Use Solid Edge for final conversion.

Tips for a successful conversion

• Always check the imported geometry for errors or missing features.
• Use Solid Edge’s Repair and Stitch tools to fix surfaces or convert them into solids if needed.
• Save a backup of your original IGES file before conversion.

Summary

Converting IGES (.igs) files to PAR (.par) format is best accomplished using Siemens Solid Edge. This ensures your CAD data is fully editable and compatible with Solid Edge’s powerful modeling tools.
