Use Dynamo to Filter out elements in view blocked by other elements

Hello Everyone.
Please I want to select some category of elements in Revit using Dynamo. Then filter out those of the elements which have been blocked in view by other obstructive elements.

Please couls someone help me out with this challenge with the Dynamo.

Thanks for willing to help.

Hello MaKarf, can you show us what you have so far?
If you dont know where to start, try taking a look at the “All Elements In Active View” OOTB node.

Ok I have not been able to do what I wanted though. But I will want to post the dynamo graph and its results here for everyone to have a look at it
