Open a IGES file
in Fusion.

Updated 2026-10-01

Fusion for Personal Use cannot import IGES files: Autodesk lists IGES import as needing a commercial subscription. Convert it to STEP below, then open the .step in Fusion. Fusion imports a STEP file as an exact solid body you can measure, cut and mate.

With a commercial Fusion subscription you can upload the IGES directly.

What Fusion can import was checked against its own documentation: Fusion supported formats. Software changes; if a newer release imports IGES directly, use that.
