Hi,

I modified default UUDD airport properly having added correct parking spots and approaches, but when opening P3D, I see a duplicated main terminal, which remains there whatever effort made to correct it using ADE 1.78. I tried every possible workaround unsuccessfully. As I ran out of ideas, any suggestion is welcome.

Did you use ADE search tool to find out which version had priority. With the tool you disable conflicting versions by deactivating them.

Thanks for your response Raymond.

Could you please let me know how can I find that tool within ADE dropdown menu ?

When in your airport. At the top select Tools then in the drop down box select , File Priority Analyzer, then scan. this will tell what`s active including the default base file.

OK, I found it but it presented 3 files plus an ALT correction file. What can I do now with  that list ? The disable-enable buttons are grayed.

Look at three files one will be your modified airport file should be active, you can only click on an active file to disable. ADE allows you to go back and re-enable if you make a mistake  

PS. One possible solution remove your custom ADE file and try again. Making sure you only save parking and taxiways, you can remove show airport buildings from the option menu.

I know it`s a pain to learn but when you get the hang of it you do anything in sim. That why P3D is sim. I have built airport that were missing in some versions from scratch. Google the info and your off headings ILS ATC info.

I did remove the custom airport abd the list still contains the same three files which remain grayed.

Please note that with custom airport removed, when open P3D, the same oddity is still there. That means the default has the same defect.

What you see here is the default three BGL files that make up the airport. they cannot be disabled. you may have a corrupted scenery file

In V5 and V6 I see no duplicate main building.

Placing a custom ADE BGL files in the sim will be above the default when loading P3D will only load the BGL files with the highest priority.

Note the bottom BGL is the APT the top two are scenery.

I finally sorted it using the ADE exclude-all function. Many thanks for your eagerness to help me out.

Finally I want to assure you that those unwanted buildings were there even using the default (stock) airport.

And a question : what do APT initials stand for ?

P.S. Apparently APT means airport, OK.

Good at some airports unwanted buildings are part of the base scenery. And ADE does not show them.
