Folding shapes - In need of an alternative way

I'm working on creating a shape which can be folded and I'm doing it using point and lines between them, which mean I need to construct points, create a line, then end points, another lines, etc. And it seems like there might be more efficient way to do this.

I'm attaching my grasshopper file, if you think there's a better way to do this I'd be happy to learn.
