• 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.

P3D v5 ACM - What happens when you change your default.xml

By the subject I mean I have been adding objects to my custom default.xml that is then incorporated into P3D's main default.xml. What happens when one modifies their file like remove an object or let's say we change the GUID (either class or the object). Does ACM edit P3D's default.xml with those changes or does it just add to the file?

If you edit the file it will merge again, checking what the differences are.

I would have to check the source to know exactly what it does when you remove a class, I think it will remove it if the classes around are unchanged. Same for changing a guid.

When you change objects in a class (adding, removing, etc.) these are just used to replace what was present for that class.
