Is it possiable to edit a 3rd party airport

I have a third party airport that I would like to remove a few static aircraft from and add a parking spot.

Is this possible with the SDK?

Would I need another tool to modify compiled scenery?

Thanks.

Hi there,
There is an SDK subcategory. I have moved your question there.

I would also like to know this. I have a 3rd party scenery that is missing some parking spots and parking/taxi markings and I would like to add them for my own use.

I’ve been able to edit some third party airports by using ExclusionRectangles, and it generally works for static planes but not buildings so much. Some editing can be done with ADE, including parking spots and taxi markings.
