Fusion 360’s .3dm import drops standalone curves, and STEP mangles them — yet those curves carry the machining intent: profiles, drill points, engraving paths. **F2F Bridge brings the whole file across.
**
uilt for the Rhino-design → Fusion-CAM workflow — and for heavy vector artwork (logos, engraving) that would kill Fusion’s sketch solver if inserted directly.
It reads the .3dm directly (no Rhino needed on the Fusion machine) and rebuilds:
- planar curves as native sketches, one per layer × plane — exact arcs, NURBS as fixed splines (no solver overload)
- non-planar curves as 3D sketches (engraving on curved faces)
- Rhino points as sketch points
- bodies renamed with their Rhino names — whether your solids came in via STEP or a directly opened .3dm
- your Rhino layer tree becomes your Fusion sketch names
