I've successfully published a web elevation layer (VA State Plane), 3D buildings, and a 3D flood layer. I would like the scene's measuring tool to enable a user to measure flood height on a building, but the tool seems to use the flood layer as the base for measurement rather than the web elevation layer. In areas with no flooding, the measurement tool recognizes the ground surface, but it doesn't recognize the ground in a flooded area. How can I fix this? The attached video shows what I'm seeing.
