Convert IG2 to IGS

Understanding ig2 and igs file formats

IG2 files are typically associated with Intergraph Standard File Format, used in older CAD systems for storing 2D and 3D design data. These files are less common today but may still be encountered in legacy engineering projects.

IGS (or IGES) stands for Initial Graphics Exchange Specification. It is a widely used neutral file format for exchanging CAD data between different software platforms, supporting both 2D and 3D geometry.

Why convert ig2 to igs?

Converting IG2 files to IGS format allows for broader compatibility with modern CAD software, easier data sharing, and long-term archiving of engineering designs.

How to convert ig2 to igs

Since IG2 is an older and less common format, direct conversion tools are rare. The best approach is to use a CAD application that supports both formats, such as Bentley MicroStation or Intergraph SmartSketch. Here’s a typical workflow:

1. Open your IG2 file in Bentley MicroStation or a compatible legacy Intergraph product.
2. Go to File → Save As or File → Export.
3. Select IGES (*.igs, *.iges) as the target format.
4. Choose your export options and save the file.

If you do not have access to these legacy applications, consider using a professional CAD conversion service or specialized software like Okino PolyTrans, which supports a wide range of CAD formats and may handle IG2 to IGS conversion via intermediate formats.

Recommended software for ig2 to igs conversion

• Bentley MicroStation – Best for users with access to legacy Intergraph files.
• Okino PolyTrans – Advanced conversion tool for complex CAD workflows.
• CAD Exchanger – Useful for converting between many CAD formats, though IG2 support may require plugins.

Tips for successful conversion

• Always back up your original IG2 files before conversion.
• Check the integrity of the resulting IGS file by opening it in your target CAD software.
• Be aware that some advanced features or metadata may not transfer perfectly due to format differences.
