perhaps ‘cage edit’ can work?

I’m taking a risk sharing this geometry. But I think it’s important.

“midline nomenclature” is mirror line. I’m trying to respect IP. Don’t worry too much about nomenclature, I can’t give everything away.

This challenge can easily increase in complexity.

I’m curious how advanced certain things can be like ‘cage edit’, flow curve, GH etc.

Cage edit is more of a ‘manual’ approach, which I think is doable if it can be advanced enough for the user – and repeatable.
