Yes, you’d get a different result. I hadn’t read your second post while I was working on this.
Do you have any control over the source geometry here? It would go a lot smoother if it was designed for manufacture from the start. A base curve and then an Extrude or an Extrude Conical would guarantee a developable surface, which could then be split up with curves (Iso and otherwise) to generate nice clean panels. You’d then use an unrolling component like this (or one of the plugins with such a component, as listed in that thread) to generate the flat shapes.
Is the fabricator on board with this btw? These are not easy shapes to make accurately!
