ADE requires the scenery it creates to contain an airport. You could load the airport into ADE and add your objects to it. If it loads after other versions of the airport then you should get what you expect.
Thanks Jon, if I do not want to attach to a existing airport, any ideas on what I can use to place free-standing buildings into FSX/SE?
I keep having fun with your program, and learning things (like new words-some useable in polite company)
Thanks guys, the item is a water tank (large) that I created years ago in FS9 and uploaded it. However, I lost the files in a computer melt down, and I just do not remember how I did it. I know it was NOT ADE! If I can't figure it out, it is no big deal, I am just trying to bring a little history to my FSX scenery.
