1- One section,One path
In this lesson, you will learn how to use a single section and a curved path to produce a parametric model. First I will explain how we can orient the section into the curve and then we will model the rest.

I am wondering. How can I get normal vector of a curve in Grasshopper?

Hi,
There is not such thing as Curve normal but you can calculate perpendicular vector to certain point by rotating tangent vector of certain position on curve.
I’ve attached a file that might help you

True. Thanks for the prompt reply. Its just because I found one node in Dynamo i.e. “Cure.Normal at Parameter” and then I started looking the same node in Grasshopper. Thanks. Nice explanation
