@parikshit.thombare8X did u check in your live model with which element that inclined point is connecting coz as in your test model it’s working fine as you created ideal conditions there. I was going through your graph
and here i could see you using this node from Datashapes
which helps in finding nearest not importantly bouncing from the element you want it to.
This could give you better result in this case by bouncing from exactly the element you want it to bounce from and also in case you mentioned looking for another way to do this ReferenceIntersector Class (revitapidocs.com) we could write our own python script as well to get it done.
Please try bimorph’s LinkElement.ByRayBounce first otherwise you can share the file as well and if it’s confidential and don’t want to share here, do inbox.
Edit:-
Datashapes also having this particular node for specifying category, Also you can refer to these threads as well RayBounce to work on linked files
Extract parameter value from one family and assign to another
