How can I make a developable surface that approximates the surface defined by these two curves?
Are there any grasshopper tools for it?
I have the eval version of eloft. Not sure how to generate a fully developable surface with that.
If you make a sweep2 with a line as cross section it will be developable. At little scale the sweep is a succession of quads and a quad could be triangulated with points which are just on the 2 curves. So it will be developable. It is a strip.
Does it help ?
You can use etLoftDevelopable in EvoluteTools D.LOFT to loft a developable surface between the curves.

A sweep2 curves may or may NOT give you a developable surface. Believing that can, in some cases, result in a very costly mistake. It is far better to use Evolute.
A sweep2 curve might give a nice looking surface, but it will probably NOT be a developable surface.
This will be painfully and expensively apparent if the surface in question is used to develop a supporting structure, such as in a boat, and in particular in the forward areas.
Transverse frames made from such a surface will prove to be impossible to use. If the surface is not developable, then it will NOT lay fairly onto to the frames.I know from experience!
