unroll double curved surfaces.

Hello guys how are you doing

I got an issue here whit the next geometry, I want to produce it and  make a model of it, but what I have during the process of it is that the different pieces of it doesnt match, some edges are larger than others, so, it doesnt fit at all.

Im doing it by getting the geometry edges and remaking the new surface and unfolding it, because im trying to aboid the segments on every single surface, but, to be honest I dont know if this is creating the error. There is any way to make it work

Here ive attached the model in rhino and the definition in grasshopper. thanks for your help
