Convert IAM to IGS

Understanding IAM and IGS file formats

IAM files are Autodesk Inventor Assembly files, used to store 3D assembly data created in Autodesk Inventor. These files contain references to multiple part files (IPT) and define how these parts fit together in a complete assembly. IAM files are widely used in mechanical design and engineering workflows.

IGS (or IGES) files stand for Initial Graphics Exchange Specification. This is a neutral file format used for exchanging 2D and 3D CAD data between different CAD systems. IGS files are commonly used for sharing models across different platforms and for manufacturing processes.

Why convert IAM to IGS?

Converting an IAM file to IGS format allows you to share your Autodesk Inventor assemblies with users of other CAD software that may not support the native Inventor format. The IGS format is ideal for interoperability and long-term archiving of CAD data.

How to convert IAM to IGS

The most reliable way to convert IAM to IGS is by using Autodesk Inventor itself. Here’s how you can do it:

1. Open your IAM file in Autodesk Inventor.
2. Go to File → Export → CAD Format.
3. Select IGES (*.igs, *.iges) as the file type.
4. Choose your export options and click Save.

This process will generate an IGS file that can be opened in most major CAD applications.

Best software for IAM to IGS conversion

• Autodesk Inventor – The native and most accurate tool for this conversion.
• Autodesk Fusion 360 – Can import IAM files and export to IGS format.
• AnyCAD Exchange – A third-party tool that supports various CAD conversions, including IAM to IGS.

For the highest fidelity and best results, Autodesk Inventor is recommended.

Online converters and limitations

There are few online converters that support IAM to IGS conversion due to the complexity of assembly files and their dependencies. If you do not have access to Inventor, consider using a trial version or contacting a service bureau for conversion.
