Grasshopper - network surface excludin a curve

Hello,

for some reason GH doesn´t accept one curve in my code an since I´m new at GH I have no idea why. It worked before with biarc curves instead of the new bezier curves (but those were ugly).

The question is how do I include the last curve to the surface? (since it´s joining the 2 objects it´s kinda important)

Check this out… The key is not flattening, but the same data tree branch…

Now that´s one useful thing to know :wink: I doubt I´d find this solution before rewatching about 10 hours of tutorials so great thanks to you!
