Convert IGS to IAM

Understanding IGES (.igs) and IAM (.iam) file formats

IGES (.igs) is a widely used file format for exchanging 2D and 3D CAD data between different CAD systems. It stands for Initial Graphics Exchange Specification and is a neutral format, making it ideal for interoperability. IGES files can store wireframe, surface, and solid geometry.

IAM (.iam) is the assembly file format used by Autodesk Inventor. An IAM file contains references to multiple part files (.ipt) and defines how these parts fit and work together in an assembly. It is a proprietary format specific to Autodesk Inventor.

Why convert IGES to IAM?

Converting IGES to IAM is essential when you need to import neutral CAD data into Autodesk Inventor and assemble multiple parts. This process allows for further editing, assembly, and simulation within Inventor.

How to convert IGES (.igs) to IAM (.iam)

Direct conversion from IGES to IAM is not possible because IGES files typically contain single parts or surfaces, while IAM files are assemblies. The standard workflow involves importing IGES files as parts and then assembling them in Inventor.

1. Open Autodesk Inventor.
2. Go to File → Open and select your .igs file. Inventor will import it as a part (.ipt).
3. Repeat for all IGES files you want to include in the assembly.
4. Create a new assembly via File → New → Assembly.
5. Use Place to insert the imported parts (.ipt files) into the assembly.
6. Save the assembly as an .iam file.

Best software for IGES to IAM conversion

Autodesk Inventor is the best and most reliable software for this conversion. It natively supports IGES import and IAM assembly creation, ensuring high compatibility and accuracy.

Alternative solutions

Other CAD software like SolidWorks or PTC Creo can import IGES files, but to create an IAM file, you must use Autodesk Inventor. For batch conversions or automation, consider using Inventor's scripting capabilities or third-party plugins.
