Fusion Integration as replacement for T-Splines?

I’ve been thinking about the tool I actually need to replace tsplines and had this thought.

Is it possible using the Fusion API to export a body ‘live’ as say a STEP file and have grasshopper constantly import the STEP file geometry.

I usually have Fusion open on my machine for CNC toolpath generation anyway. With a couple of what sound like basic scripts to automate the export/import (or data exchange) Fusion/Tsplines would become a another ‘tool’ in my Rhino work flow.

Anyone else keen for such a setup?


Seems data export can be scripted in F360
