Transfer a line in Dynamo with a turn

Hello to all Dynamo users! I have a question by geometry. Does anyone know how to transfer a line in Dynamo with a turn from one end point to another? Or build a new line in a new place with identical curvature of the original line?

What is the output of this node?

Instead of one single bended curve, connecting two points, the program draws two parallel curves from each point.

I am not quite sure what you’re asking.

But I am guessing the output of the node I circled has something to do with your issue.
