Now, it gets confused... Let me see if I understood: You are trying to say that you still have AI traffic when you use 1 width taxi lines? Is this so? Sorry, I lost something then... Then where is that file you posted with 1 feet width and all traffic? Can I try that one as well?
Yes, of course, you might have missed the messages posted here:
http://www.fsdreamteam.com/forum/index.php?topic=1770.msg14114#msg14114That screenshot was taken using one of your AFCAD (the current version at the moment of that post), just changed with links in proximity of hold short zones to 1 ft.
We released the scenery with an AFCAD made like this, I guess that if that affected the AI traffic, we would have had thousands of reports of users losing AI, by now...
There is one thing that I didn´t understand: what is the influence of having 1 or 100 feet width in the scenery? Does it matter? I ask this because I don´t have any changes in the scenery at all...
You should see a difference, that's another strange thing you are having. When the width at an hold zone is set to a normal value, the default hold short marker will be shown. And, this would conflict with the custom hold short zone marker we have in the scenery, because you would see both. By setting the width at the link close to the hold short node to 1 ft, the default marker will not be drawn anymore.
Now, there's still something that is not 100% clear, is if setting the width on *both* sides of the hold short marker to 1 ft makes any difference on AI behaviour. It doesn't on my machine, using the AFCAD I've posted on that thread. However, Mike says he sees AI bunching up at hold short zones, if the width is set to 1 ft to both sides of the marker. But, perhaps, this happens with his AFCAD only, because he removed the Aprons, that sets the surface type and act as a flatten as well, and are needed because we don't have real "taxiway" links to set the surface type, only "apron links", so this *might* have an effect on the AI behviour at the hold short zones.
I don't see such issues with my AFCAD but, if setting the width to 1 ft only to one side of the marker it's enough to get rid of the default hold short marker, so be it...
