• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

edit an airport.bgl file

Hi folks

I read many posts here about .bgl and .cvx files, about loosing data while "open" a .bgl

What I want to do:

I want to edit a downloaded "from AVSIM" airport .bgl which an other fellow simmer has created. For example changing parking sizes, adding more parkings.

Since there is no .ad3 files I have to open from .bgl
I see, there is also a .cvx file for that airport.

So how I dont "loose" the data from the original .cvx file if I do / have to "open from .bgl"?

Thanks for your help

Copy the .cvx file to a safe place on your computer.

Open the airport by way of the bgl and save so it creates a .ad3 project file. All work will now be done in the project file.

When all your changes are done and you have a new bgl file copy the original .cvx file back into the active folder.

Make sure you keep a copy of that CVX file safe somewhere. If you later forget and compile your AD3 file directly into the scenery folder, the CVX file will be deleted. You'll need to copy it again.

I keep such files in the scenery's main scenery folder (i.e. the parent folder of the scenery and texture folders). That way it's handy when I need it.
