• 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.

runway extension into water looks fine up close, but collapses flat the further you get from it...unacceptable!!!

This is driving me bonkers.
i make a flatten for the airport.
i make a slightly sloped edge around the end of the runway protruding into the water.
i have a cvx for the water all around the edge of the runway extension.
i have a no water polys polygon on the land side.

this is correct, this is what i want. BUT!!!!!!!
if i go out about a mile away. it starts collapsing, and its very plain to see...especially when on approach, the pilot can see this malformed mess of a shoreline , EVEN WITH A WATER CVX, it starts making itself into a giant bulge!!!
the furthur away i get, the flatter it gets....

then it starts building itself back into shape...and as the plane get closer and closer ---this takes time --- apparently the processing speed of the computer maybe idk.

the bad part is, that while on approach the pilot can see the coastal edge and how it looks like flat, and while flying towards it , watches it build itself back into a nice looking edge. BUT THAT'S UNACCEPTABLE!

this is what i get when i slew back real quick, before the computer can process the mesh back to its original state...

Why is it doing this>>>>>>>???? spend hours and days getting it to look right , only to go out away from it about a mile or so and the whole thing turns to muck and collapses flat. i have tried for weeks now and i cannot for the life of me figure this out...

PLEASE!!! iF YOU KNOW HOW TO SOLVE THIS PLEASE HELP!!!!
thank you!
 
Hi again:

Were your CVX vector BGLs cited in the OP above created / output by SBuilderX ? :scratchch

If so, you should be able to output from SBuilderX, ESRI *.SHP data that can be imported to Sketchup via a plugin, to reduce work load required to otherwise re-create the airport as a 3D model. :idea:

Otherwise, you can use Patrick Germain's CvxExtractor to decompile any 3rd party CVX vector BGL files created in ex: ADE, then output ESRI *.SHP data that can be imported to Sketchup via a plugin, to reduce work load required to otherwise re-create the airport as a 3D model.

I can provide you with details on a particular Sketchup plugin and work-flow to import / process the ESRI *.SHP data. in the event that you are inclined to inquire further about this option. ;)

thanks gary,
i think the best way for me would be to model the part in place on the maps, to the correct height, texture and use the make platform in the effects editor. then it will automatically get placed via the coordinates where its sitting on the map when i export it.
does that sound like a "just as easy solution"? one problem i can foresee is that the whole waterfront will need to be modeled because the whole thing collapses at distance.
 
That certainly could work as well.

Alternatively, you could import the *.SHP files which, IIUC, were also traced over an imagery background Map.

One must ensure the *.SHP file data set derived from the CVX BGL(s) is re-projected from EPSG:4236 to EPSG:3857 for 3D modeling.

After imported to Sketchup, the *.SHP file objects derived from CVX vector data could then be moved into position, and the vertices fine tuned as needed to align with the imagery, extruded to height for the central airport flatten area, and that could be intersected with an imported terrain data set to make a sloped flatten that blends into the surrounding terrain mesh one intends for use in FS.


Feel free to inquire further for more info on importing CVX terrain / GIS data into Sketchup via 3rd party plugins. :)
