Congratulations, Dave. Keep at it and soon you will be answering the questions here!I also noticed that the braces were not always needed. No idea what that means.As for where to put the bgl, it really depends on you. There is no particular requirement, in spite of what the S.D.K. documentation may say.The folders have no special characteristic apart from their layer. That is, folders at the bottom are loaded first in game, and those loaded afterwards are drawn over them. Other than that, it doesn't really matter where you put the file.The only exception is with excludes (they only remove what has been loaded before them) and airport altitudes that have changed (and the new altitude file must be loaded before the default file.)Best regards.Luis

Hi Dave,first time for me that I get a "Thank You" for questions ;-))It seems you are a nice guy.Wellcome in the world of scenery-modification.Since Luis answered my questions in that wunderful manner I stick on my PC an create my new small worlds.Best regardsBodo
