Here is part of the code from a FSSC generated bgl. Excluding STANDARD fs9 GENERIC BUILDINGS CREATES A MORMAL SERIES OF EXCLUDES AND A GENERAL OVERALL EXCLUDE WHICH WIPES OUT MY AFCAD REDESIGNED AIRPORT. THE WORKAROUND IS EASY....SIMPLY DELETE THIS PARTICULAR BGL.HOWEVER I AM STILL CURIOUS ABOUT WHAT THIS CODE DOESHERE IS THE TEXT OF THE FIRST PART OF THE BGL; ************************************************************; Scenery compiled by FS Scenery Creator 1.5.11 by Derek Leung; Scenery compiled on 6/15/2006 7:00:01 PM; ************************************************************Set( buf 100 )Set( areamx 64 )Set( linbuf 64 )Set( ppperr 2000 )UVar( $FSSCTEMP1 5 )Header( 1 N44:44:34.4222 N44:12:10.5775 W072:46:42.4061 W073:32:06.4952 )LatRange( N44:12:10.5775 N44:44:34.4222 ); Header ExclusionGenExcl( "C:DOCUME~1JOHNC~1DesktopAA_KBT~1SceneryAAAA_version 2_exc1.bgl" 1 N44:44:34.4222 N44:12:10.5775 W072:46:42.4061 W073:32:06.4952 N44:44:34.4222 N44:12:10.5775 W072:46:42.4061 W073:32:06.4952); Exclusion 1GenExcl( "C:DOCUME~1JOHNC~1DesktopAA_KBT~1SceneryAAAA_version 2_exc2.bgl" 1 N44:28:40.4481 N44:28:24.2495 W073:08:40.2572 W073:09:02.9572 N44:28:40.4481 N44:28:24.2495 W073:08:40.2572 W073:09:02.9572)........................................WHAT EXACTLY IS A HEADER EXCLUSION?

Hi John,I have no idea what header exclusion is, it must be a term of FSSC itself. It seems that the first exclude in your file covers the entire area (as defined in the header) of your scenery. This could indeed have a very big effect if this is a big area. It is some time ago that I used FSSC myself, so I can't remember if it puts in things like this automatically.
