Library for Civil Python

Hi!
What library I should import to use Geometry operation (StartPoint, PointsAtSegmentLengthFromPoint etc.) in my Civil Python script?
I tested plenty of different scripts including default Python template and Dynamo Examples, with no result.

nq1

I suppose something like this might work

Your input seems to be empty. NoneType…

I believe all my input is fine)

What you connect to python node, I meant.

In fact, I really got mixed up in my connection nods when I took a screenshot. But it doesn’t matter in this case.
nq4

I’m trying to port my code from Dynamo Revit to Dynamo Civil, and below my civil Python test script. And I realized that a StartPoint function work well
