Can I easily convert .iam files to .stp format.
Converting Autodesk Inventor Assembly files directly to STEP 3D CAD Files (.iam to .stp conversion) should be easily accomplished using the original software, Autodesk Inventor.
There are, however, other CAD/3D modeling tools that support Autodesk Inventor formats. These should also be capable of exporting models, or parts from .iam files, and saving them in .stp format; ISO-10303 STEP product data files.
