I'm more worrying AFCAD modifications
Then you don't need the DONTUPDATE at all, as I've said.
With all due respect FSDT is a way far behind in terms of proper coding, taxiways allocation, parking types and radiuses and too many other small items to mention. I'm not blaming anyone, just suggesting to leave that area to the users (if they want to)
Are you referring to old sceneries ? Because, all our recent sceneries have proper coding, proper taxiway allocation, proper parking types and proper radiuses and, in fact, the reality is exactly the opposite and, while working on GSX, we found most of the problems you are reporting, are happening with *other* sceneries, which are full of error.
And "far behind" compared to what ?
To what other scenery developers do ? I don't think so, just have a look at the GSX sharing forum how many things Cartanya have to fix in *other* sceneries.
To what you could do by yourself ? In this case, if you have something to say about an FSDT AFCAD, please post it in its appropriate section, indicate each and every problem, post your considerations on why you think it's wrong, and we'll go through them, one by one, fixing what really needs to be fixed.
