Using Exclude Areas to Remove Bushes?

[LTCSZ]

I have been updating some P3d airports with additional ramps using ADE but have been running into the problem of bushes, trees and so on sticking up into the ramp from the underlying scenery...I am familiar with the Exclude Areas feature of ADE, but it does not include bushes and trees...Is there a way to hide the underlying scenery? Thanks a lot,

You need to use a terrain exclusion polygon to remove these.
