Not daft or ignorant at all! And you don’t need any AI background to understand it.
To answer your question; this isn’t intended as a Grasshopper competitor. It’s simply a native Rhino plugin that exposes existing RhinoCommon functions in a parametric way. Just like the node editor in Blender, it starts up automatically when Rhino launches. Anything you usually do with standard Rhino commands, you can now build parametrically with nodes, create custom plugins, and test them live in real-time.
Sounds like a more direct grasshoper without the layer of separation ? What happens to the parametric aspect if you edit the Rhino geometry directly (eg delete faces etc) ?
Not quite , it’s still node-based and parametric, just like Grasshopper.
Same behavior you’d expect from any parametric/node-driven pipeline: the geometry shown in the viewport is generated live from the node graph via a display conduit , it’s not baked Rhino document geometry until you explicitly bake it. So editing it directly (deleting faces, etc.) doesn’t feed back into the graph; the next graph update will just regenerate the output and overwrite any manual edits.
