• 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.

FSX generic building position problem

The problem of floating generic buildings in FSX is known, but I have a problem I haven't seen before. I am working on WBGG, and the generic buildings are are positioned 8 meters north of where they should be from the bgl data (looking at both stock airport and newly added generic buildings). Can someone confirm this or have you seen this anywhere else?

Scott,

i see nothing unusual there at all,
only the jetways that are not connected to the terminal,
and i've seen that at many airports
everything in the surrounding area look fine as well.............
28 of them in the airport are in what i would consider the correct place,
which buildings are you talking about any particular ones,
the bunch at the terminal looks ok.......

Well the jetways are not connected to the terminal, because the terminal is not placed correctly. Load the stock WBGG into ADEX, and the terminal looks correct relative to the apron and jetways. Then start FSX and connect and you can slew over the corner of the terminal and see that it isn't where ADEX says it should be.

Is this the problem we found with FSX (which we have no answer for) where the placement of generic buildings in sim does not match the placement in the design tool? Works fine in FS9 but they are all off to some degree in FSX....

Scott we were discussing this recently in beta but you may have missed it. We have not found a solution for why FSX is out of sync with generic buildings at some airports but not others. I do know that Geroge and Jon were looking into the problem and WBGG could be a good canidate to why it is happening.
 
Must have missed it. I've seen many cases of floating buildings, but didn't realize it extended to placement as well. It's nothing wrong with ADE -- you can look at the generic building xml straight from the original bgl and ADE places the building right where the xml says it should be. And the aircraft position in ADE agrees with what is shown in FSX which I thought might be a cause -- and you can see that everything else is placed perfectly, just the generics.

I didn't look closely, but I don't think it is a scaling issue of the building, it is a pure translation of position. In the WBGG instance it appears to be exactly N-S direction, but don't know if that is the case at other locations.

You are seeing what I am seeing Scott. I think it may be to do with the round earth model but I could not say why. If the error is consistent against some parameters like lat/lon then we could build the correction into ADE perhaps.
 
it's not just the generic buildings,
take a look where the red dot is in the library object "Fire Station huge"
now that's what i call off center :)
always a problem trying to put an apron around it or line it up alongside a generic building that's also out
 
I think there's always the problem of the reference point of a model is placed in the mdl design and unless you draw the actual wireframe (that ADE does for jetways) it's hard to say where the actual placement will be.

ADE in the later versions does place the reference point exactly where it should be in relation to the model. The small red dot that shows in the footprint when the object is selected marks the exact origin of the model and in some cases (fuel pumps for example) this is outside the footprint. As far as I know ADE places library objects exactly. The problem with generic buildings is that we have to assume they are drawn around a reference point at the center of the footprint. There is no way in the XML code to check or change this of course.
 
Don't know since Scott has not posted lately.

I do see him post at Flightsim so you can check there.
