Your Make2D.gh file looks like a significantly different problem, using solids instead of surfaces. Might have additional comments later… (why such complicated geometry?)
My limited experience with Make2D was not pleasant at all!
While the curve from Make 2D is good, I was amazed and disgusted by how incredibly difficult that component is to use
Wow, what a pain!! I finally found something here, which I adapted, but it wasn’t easy at all:
As to my earlier effort in this thread (version Oct1a), I’m not so sure it is correct. For one thing, there is no reason that extrusion distance should be driven by Series. I believe this version makes more sense, using ‘(numSrfs+1) * step’ instead:

Even so, there might be cases where it fails?
