I wanted to edit KMDW ( Chicago Midway airport) , but its a huge, complex airport, and all i want to do is keep everything the same ,except get rid of the over sized control tower, clean out some vegetation next to it , and change some of the hangars into more accurate hangars.
Can i just create polygons within the airport over these structures and exclude everything inside ? and then put my edited structures on top ?
Will that work, to have most of the default airport as is and just add my edited buildings on top ?
