Convert IAM to 3DM

Understanding IAM and 3DM file formats

IAM files are Autodesk Inventor Assembly files, used to store 3D assembly data, including references to individual part files (IPT) and their relationships. These files are essential in mechanical design and engineering workflows, allowing users to manage complex assemblies in Inventor.

3DM files, also known as Rhinoceros 3D Model files, are the native format for Rhinoceros (Rhino), a popular 3D modeling application. 3DM files are widely used in architecture, industrial design, and CAD for their ability to store NURBS geometry, meshes, and other 3D data.

How to convert IAM to 3DM

Direct conversion from IAM to 3DM is not natively supported by most software, as these formats are designed for different applications. However, you can achieve this conversion through an intermediate format, such as STEP (.step, .stp) or IGES (.igs, .iges), which are supported by both Autodesk Inventor and Rhino.

Recommended software for conversion

• Autodesk Inventor: Export your IAM assembly to a neutral format like STEP or IGES.
• Rhinoceros (Rhino): Import the STEP or IGES file and save it as a 3DM file.

Step-by-step conversion process

1. Open your IAM file in Autodesk Inventor.
2. Go to File → Export → CAD Format and choose STEP (*.stp, *.step) or IGES (*.igs, *.iges) as the export format.
3. Save the exported file to your computer.
4. Open Rhinoceros (Rhino).
5. Go to File → Import and select the exported STEP or IGES file.
6. Once imported, go to File → Save As and choose 3DM as the target format.

Best converter recommendation

The most reliable method is using the combination of Autodesk Inventor and Rhinoceros (Rhino) for conversion. For batch or automated conversions, consider using Autodesk Inventor Professional with scripting or third-party plugins, or Okino PolyTrans for advanced format support.
