Converting pointcloud to Revit geometry (Creating modelline from pointcloud)

Dear all,

I am creating a cross section within an interval of 10m from pointcloud in Revit 2021. I have been using Dynamo for repeated tasks and here I am enquiring about if there is any method that I can simplify the repeated task of drawing a model line along predefined reference level.

It would be much appreciated any contribution and guidance towards solving the problem. I have attached a screenshot for hoping that would bring clarity to the question that I am asking.

Thank you so much in advance.
