Select LIDAR points above user-created polygon shape?

Hello All-

I'm working LIDAR points for the first time and am running into problems. Any help would be appreciated.

I have a set of first return points representing tree tops, roofs, etc. These surround an airport.

I also have a 2D curved shape (built in CAD, in .dwg) that was built based on federal guidelines. It represents a 2D plane above which there should be no objects, lest they interefere with the airplanes' taking off and landing. Imagine a long thin bowl that extends from each end and sits on the ground surface.

I need to select those points from the LIDAR shp that are higher in elevation than the polygons that make up the boundary.

Any thoughts or advice would be welcome.
