What is an IAM file?
An .IAM file is an Inventor Assembly file. Autodesk created this format for Autodesk Inventor, a professional 3D CAD program. The .IAM file connects multiple 3D part files (.IPT) to create a complete product design. It stores the position, constraints, and relationships of each part, rather than the physical 3D geometry of the parts themselves.
How to open IAM files?
Normally, you open .IAM files with Autodesk Inventor. Other CAD software like SolidWorks or Fusion 360 can also import these files. To view the complete assembly correctly, you must keep all the original .IPT part files in the same folder as the .IAM file.
Best practices and conversion
If you need to share your assembly with someone who does not use Inventor, you should export it to a universal 3D format. We recommend file conversion to sensible target formats on convert.guru. You can easily convert your .IAM file into standard formats like .STEP, .IGES, or .STL for easier sharing and 3D printing.
Inspect files with viewer.online
Sometimes, you receive an unknown file or do not have expensive CAD software installed. viewer.online/iam analyzes .IAM files to identify their exact format and creator software, shows which programs can open the file, and usually previews it directly in your web browser.
Summary
Because .IAM files use the known DOC format structure for their internal data storage, viewer.online/iam can safely open and display them online, eliminating compatibility problems.
