https://community.esri.com/t5/3d-questions/3d-polygon-with-a-sloped-curve/m-p/1410207#M5003 <P>I have been tasked to determine what trees near an airfield need to be trimmed. (They don't want the trees removed). There is a large area of trees that are starting to enter into the flight path, and it is becoming a concern. My thinking process is to create a 3d polygon with the base of it being sloped to the requirements of the flight path. Every 37 ft it goes up 1 ft.&nbsp; Lay the 3D polygon over the las file and see what areas are protruding into the polygon.&nbsp; I was able to create a 3d polygon and add the las file. but I cannot seem to figure out how to make the base of the polygon with a curved slope.&nbsp;</P><P>Has anyone worked on a project like this that could guide me in the right direction? Or am I going about this all wrong and there is another simpler way?</P> Tue, 16 Apr 2024 13:22:36 GMT JonathanDiLella 2024-04-16T13:22:36Z https://community.esri.com/t5/3d-questions/3d-polygon-with-a-sloped-curve/m-p/1410207#M5003 <P>I have been tasked to determine what trees near an airfield need to be trimmed.
