Get height from tin at specific coordinate(s)

I need to get the height from a tin for a given point (or a sequence of points) using the ArcGis Pro SDK.

I successfully created a tin layer with the 3D Analyst Tool "Create Tin" and it looks very good in ArcGis Pro. But now I wonder how it's possible to actually get a height value from this layer? I'm aware of "Intersect3DLineWithSurface_3d" but that seems like overkill and I'd prefer to do it in plain code instead of calling a python function.


Also: Extracting the polygons from the tin via the "TIN Triangle" tool gave me the tin as polygons and I tried to intersect a polygon with a polyline representing a vertical ray.. but I had no success in obtaining the height.



Any help would be greatly appreciated. Thanks!
