What started out as a simple AFCAD Adjustment

Has turned into me wanting to redo the whole airport includeing the main terminal and cargo areas
what are some techniques you scenery pros use to remove default buildings? I just want to remove them so I can make the tarmac bigger as the default one is much to small,then I plan to replace them with an object placer.
I have EZ-Scenery but it only moves/removes what was placed with it
