Convert f3z to step or iges
F3Z is not directly exportable as a single-step conversion — it must first be unpacked and opened in Fusion 360, then exported. STEP is the preferred neutral output; IGES is a legacy fallback for older downstream tools only. The workflow is straightforward but the format distinction matters: F3Z is a container, not a solid model file.
Evidence
- The F3Z format is Fusion 360's compressed project archive (.f3z), bundling multiple design files and full parametric history into a single package.
- To convert to STEP: open Fusion 360, use File > Open to load the .f3z archive.
- For IGES: the same File > Export path applies, selecting IGES (.igs) as the type.
- If Fusion 360 is unavailable, Datakit's CAD convertor suite (updated April 2026) supports .f3d to STEP conversion — but lists .f3d (single design), not .f3z (archive).
- Per the ExportKit guide (April 2026), F3Z supports both import and export within Fusion 360 as a native backup format, but the geometry itself must be accessed by opening the archive in Fusion 360 first.
