once you add a scenery object to a certain location at KEEVIL, then close your Instant Scenery and add KEEVIL to FS and it compiles the data... you CAN NOT delete objects the next time around. it becomes 'embedded' scenery objects. Meaning that Instant Scenery, Abacus EZ-Scenery, RWY12, will only READ these objects as it would for houses, trees, existing light poles, "existing items"; it will only concentrate on what NEW things you add this time around.
HOWEVER!!!!!!!!! in the case of EZ-SCENERY, if you do not compile your objects into 1 .bgl file but have 100 .bgl files to make up the whole project, then you can selectively remove the offending object file if you so named it when you added it to your Keevil scenery / scenery folder.
example:
Addon scenery / KDVI / scenery / tower.bgl
light_pole_1.bgl
light_pole_2.bgl
helipad1.bgl
helipad2.bgl
if there is a problem with any of these, i know exactly which one to go to to delete.
Unfortunately, it looks like you may have to *MOVE the entire KEEVIL scenery folder to your desktop* - start flight sim and tell it OKAY! (because it will say it can not find your scenery). go to the scenery library and DELETE it from the list. RESTART FS9 and let it rebuild the scenery list.
Now the fun begins. Go to your desktop and get the AFCAD file for your airport and put it back in ADDON SCENERY / KEEVIL / scenery folder. --- ADD KEEVIL BACK to Flight Sim, and restart 1 more time.
this time go rebuild your airport in Instant Scenery AGAIN from scratch.
I know you hate hearing this, but this is about the only way to really do it. I have had to do this about 400 times to 1 airport that I ultimately gave up on all because I could not get the Hangars to line up correctly. >:( >:(
