Modify floor sub elements



Anybody know of a method to modify the floor sub elements in Dynamo? The points and the split lines that can modify the shape of a floor.

I have a point cloud with floor heights at certain points. I would like to import this cloud directly to a floor element. Similar to how you can import a points file to make a toposurface in Revit.

Or maybe someone could give me a hint to how to use the Revit API to do this?

Many thanks
