Hello my friends. I'm learning to modify FSX-SE airports with the ADE 167. I really researched the Internet helps but I would like to know the difference between: Exclude AutoGen, Flatten, Flatten Exclude AutoGen, Flatten Mask Class Map, Flatten Mask Class Map ExcludeAutoGen, Mask Class Map e Mask Class Map ExcludeAutoGen. You can take the doubts that I have? Thank you so much.
