Open a Parasolid file
in Fusion.

Updated 2026-10-01

Fusion for Personal Use cannot import Parasolid files: Autodesk lists Parasolid 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 .x_t directly.

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