Thanks GB,
I'm having a lot of difficulty adding a simple airstrip, so far, (4 days and nights) I have not had any success in flattening or excludes or simconnect working or polygon textures working, or background images or anything.
The only thing I got to work so far was a flatten using FSSC which isn't even supposed to work for FSX.
If I don't have any success today, I'll start another thread because I'm not used to this level of punishment.
I'd like to create .bgl based scenery, no config edits required to install the scenery, just to be able to add it under scenery library without further ado.
Edit: It seems SBuilderX won't run because it can't find FSX on this computer, which is odd because I just did a fresh and valid FSX install

I followed SBuilderX's pdf instructions for installation.
