• 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.

ADE island help?

Hi everyone!

I'm trying to design a small island in the middle of the ocean. I have done the following:

- Created a small exclusion polygon to remove the water from the QMID tile.
- Covered the entire QMID tile with water again using a square polygon of oceanic water.
- Added a landclass polygon to represent the island

...here's my ADE project:

The only thing that shows up is the runway/taxiways - no land. I think this is because the water is covering the landclass. So, my question is:

In ADE, can I create a polygon hole which punches through the water polygon? How do I continue making my island?

Thanks!
 
AFAIK, you must:

1. Remove the water with a small exclusion poly.
2. Create the island by creating a "doughnut" shaped water polygon (with a seam on one side).

Hope this helps,
 
OK, that's great, I used that technique to make my scenery:

It was a bit awkward but it looks fine. The only thing is that the seams cause the water polygons (I have about 8 of them in the end) to overlap in places, and each polygon overlaps with itself a bit at the seam. Is this a problem? Nothing shows up in the sim but it just doesn't look too neat in the editor.

It would be great to allow for polygon holes to be created like in SBx or FSX KML (hint hint, developers!)
 
Hi,

Yes, a Hole feature would indeed be nice. I've never had a problem with the overlapping polys along the seam(s).
 
OK, good to know :) Another question: I'm adding some terminals/generic buildings to the airport on the island and I'm having a problem with the generic buildings - they float about a metre off the ground. Since there's no way to control their altitude, is there a fix?

Thanks!
 
Unfortunately not. This is a bug in FSX - I assume this is for FSX? If you have floating Generic Buildings then the best advice is to try and replace them with Library Objects
 
OK, that shouldn't be a problem, there should be something in the library I can use! While you're here, I wonder if there are any plans to add a 'polygon hole' function to ADE? Would it be a large task, or a simple update? It's also be cool to be able to create a path from the vertices of a polygon too!

Thanks, appreciate it!
 
Do you mean one poly inside another? Or I think you mean creating a poly with a hole in the middle - I am not sure that is possible - the compiler needs a contiguous set of vertices. It is possible to copy one vertex exactly on to another now and thus make a join 'seamless'

Jon,
could you quickly explain how to "copy a vertex ....."? I expect you have mentioned this earlier but I seem to have missed it.
 
<Ctrl> Left-click when on the polyon (tooltip showing) inserts a vertex. Wnen a vertex is selected, <Right-click>->Copy Coords, <Right-click>->Paste Coords.

I'm not sure how it works, but in FSX KML you can create an island by making a water polygon and then placing another polygon on top of that and designating it as a 'polygon hole':

I think you can do something similar in SBuilderX. I assumed it was a built in polygon tag which you could designate in the same way as landclass or exclusion rectangkes etc..., but it's possible that the developers of these programs somehow created the feature themselves.

Thanks, I didn't know about the copy vertex thing!
 
George has pretty much said it all. You can select an object - existing vertex - Right Click > Copy Coords. Now select the vertex you want to co-locate and Right Click > Paste Coords.

I am not sure at all what the Polygon hole is. Perhaps someone with more knowledge of this than I can explain. I wonder if it is just a terrain poly of another type laid over or something else entirely
 
The "hole" is just a polygon associated with another polygon with a "subtract" attribute. At the end of the day, it is generated as a single polygon by having two coincident pairs of vertices one pair on the outer polygon joined to the other pair on the inner.
 
Hmm, just looked and there's no 'copy coords' for me. I'm running ADE X 1.61.5220. I selected a polygon then right clicked on a vertex, here's what I get:

The vertex mustn't have been selected. Watch for the tooltip then left-click to selected it before the right-click.
 
It's definitely selected! The tooltip's there in the background too:

More specifically, my version of ADE X is 1.61.5220.24064
