• 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.

ad2 file format

Is the structure of the ad2 file format public information?
I'm currently creating a "one click hangar" tool for SketchUp (current version in the SketchUp forum), and I'm planning a feature to read AFCADs and place hangars automatically over parking spots which are located inside hangars.

The tool could always do this by reading bgl files, however ad2 files would offer much more flexibility, because of the comment field for each park spot (as far as I am aware, the comments are left out of the bgl files after compile in ADE).

Well the file you see is binary serialized and compressed. It is not something that you would be able to read very easily. Also it is now replaced by the .ad3 format which is different.
