PI on alignment

Hi everybody!
Is there a way to extract the PIs of an alignment with Dynamo? I wish I could have a list of points highlighted with triangles on civil.

PI alignment.dyn (28.0 KB)
Base CAD.dwg (3.6 MB)

I did not understand you well
is this what you want

Hi thank you for reply.
not really … I would like to have only the PIs (highlighted in red in the image).

There is a node in the Civil 3D Toolkit (look under the AlignmentExtensions shelf) to get the PIs of an Alignment.
