• 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.

AGN file attached (rename ".TXT" to ".AGN".

Any ideas?

I'll have a look, but I was away for my work the last week.
 
There is a different error when using the latest development release:

G:\ModelConverterX>agn2txt X:\EnglandAndWalesV3\Texture\010331301223121AN.AGN

Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object.

Still an error, so I'll check what's going on.
 
George,

It seems the attachment is gone, which means I can't debug the issue. Can you add it again?
 
I think the problem is to do with the AGN2/A2GE sections, they all have different lengths.
 
Nope, it was something much more stupid. The tool couldn't handle the AN at the end of the filename, it expected an. I have fixed it now so that it works with any case. New version will be online tomorrow.

Thanks Arno. It is working fine now. The different section lengths are because some sections have an orientation vector.

I have edited the Wiki page.
