• 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.

Exclude Autogen - min size

I've been playing with exclude autogen polys. Some strange things I've found that are obviously not strange to Jon.
The minimum autogen exclude polygon size that works is 800sq ft. A 700sq ft polygon does nothing, anywhere. Even the 800sq ft polygon only works when it's wholly inside of the grid lines in ADE. Cross the line and again, it's useless for excluding autogen.
So Jon, it begs the question; just what are those grid lines? The one occurrence of 'grid' in the manual doesn't say anything about it.
 
The lines in ADE? Well they are just a grid that represents latitude and longitude. They are not related to any of the areas that FS uses to determine coverage of things like terrain exclusions. So I have nothing helpful to say :o Sorry
 
Oh dear, so tomorrow I have to play with TmfViewer.
I was puzzled why the grid is 0.5nM by 0.22nM.
Meanwhile a pint of Guinness is calling.
 
I think those exclude autogen polys are clipped at the QMID 11 boundaries. Assuming you are correct about min size, I could see that the poly might be clipped and the results are too small to take effect. Look at the poly in TMFviewer with QMID11 grid set and check it out.

Not the QMID11, the QMID15;

Hi again,
Funny thing. If I make the exclusion rectangle larger it works! This needs some further testing.

And from rhumbafloppy;

Hi Luis.
It almost looks as if a whole LOD13 must be within the exclude, or it doesn't work. But even that is not precise. Perhaps some autogen overlaps those bounds with some sort of refpoint that is still within the adjacent LOD13 area?
Dick

and from Luis;

Edgar found that a BGLComp exclude would not exclude autogen unless an entire LOD 13 Area (quad 15) was covered.

And then it all went quiet for four years.
Oh well, no tree lined taxiways unless I dig out autogen annotator or physically place library objects.
