Dear Rick,
I apreciate that you want to help me but don't realy understand what exactly do you want?
1.
We still don't know exactly what you did, because you refuse to allow us anything but your interpretation
I don't understand from where did this came from! I replied to every single question or doubt in regard to my doing.
2.
and with no screenshots, no description of your procedure,
What screenshots? I don't get any error messages to post them in a screenshot.
I described step by step what I am clicking in ADE! Perhaps a video would have been way better but your statement is way off.
3.
coded personal abbreviations,
Yes, it was one mistake I have done in using the wrong abreviation for an airport (I appologizued for that). Newertheless if you read that I "compiled the ARP with ADE", you would have guessed that I compiled the Airport and not only its reference point

.
But yes, it was a mistake!
4.
we don't even know what simulator you are developing for.
The problem I face is within ADE and has nothing to do with the simulation platform. Newertheless to answer your Q: It is P3Dv4.3!
5.
We know it doesn't work, or didn't, didn't work the way your interpretation expected it to work.
True, that'S why I ask for help.
6.
It was really, really difficult to come to my conclusion given the information, but then I got a clue:
Your clue is pointless and you interpretation of what I wrote is wrong!
When compiling the airport with ADE you can choose either to compile everything in
ONE .BGL file (including the objects, ground poly, and so on) or to compile all those in sepparate files which I always do. Thus I always get a sepparate .BGL file for my objects which is called
Project_OBJ.BGL! So I did not want to create any Library or else
7.
but that is not the fault of the developer, nor is it ours and it is not how any versions of the Microsoft flight simulator I am familiar with work.
Your statement is again a bit off. I newer said it's any DEV's fault or that the sim is broken. I came here with a problem and asked if I was doing something wrong!
8. In your first post you write:
I don't use ADE for object placement,
Well how would you know what I was doing wrong if you don't use ADE for object placing at all.
Have you tried to open a stock airport, place an .MDL (by the book), save the airport, close and reopen ADE to see if the object (Model) is still there? This would have taken you max. 5 min.
I have a mixed feeling that you realy want to point out that I doing things wrong without even knowing or understanding what I'm actualy doing.
stupid question Ger, when you add the models to the ADE models list (file) you are saving that list again arnt you?
It's not a stupid Q but yes, I did press the "Save List" button.
I also tried every single tip you have gave me.
Best regards,
Gerald
