• 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.

GP Polys superimposed

Hi, keeping in mind that currently GP Polys do not have coordinates positioning, I'm searching for a possible "trick" to superimpose exactly two or more ground polys without copying every vertex coordinates one by one that could be extremely uncomfortable

Thanks a lot
 
Select polygon > go to vertex 0 > keep your cursor on the vertex, copy the polygon, keep the cursor on the 0 vertex and paste. It will be 99% perfect superposition but not 100%. So what I do and that is indeed more work, is to make a new poly with roughly the same geometry, slightly smaller with the same number of vertices and then copy and paste the coordinates to match the underlying poly.
 
How exactly is exactly? One way is to select the GP Poly and copy it. Then paste it, zoom in and bring the second copied one exactly over the first. The other way is to select the first poly and use File > Export ADE Objects and save the export file. Now go to File > Import ADE Objects and select the file you just exported. This will copy back in the poly in exactly the same place. Import 10 times and you have 10 identical polys superimposed on each other. They are the same of course but you can then edit them - being careful not to move them - with any new information or changed properties.
 
Scruffy, the first way you proposed is the one I used till now, but in some cases it is not so "exactly" superimposed and it could leave some borders visible.

Wonderful, thanks a lot, I'll make a try with the other ways [emoji106]

Hi, I tested this method but I noticed that there is a little difference in the way ADE 1.70 works compared with the preceding 1.67 version.
With the latest version when you paste a copied object, it is pasted using the geometric center of the object and not the vertex "0" as happened with 1.67.
If I may express an opinion, that behaviour was better because the "0" vertex is always identifiable instead of the geometric center that in case of complex poly is impossible to find for reference
 
In order that the program can handle multiple copy/paste it needs to work around a given center point which is the geometric center of all the objects selected. If one is selected then it is the geometric center of that object. I would recommend using the export/import method suggested in my post above. This remembers the coordinates of all the vertex points so on importing back it will be exactly identical in position and shape to the original.
 
I had not copied any poly's anymore the way I explained first because it was always slightly off afterwards.
But thanks Jon, for pointing out this export/import method. I had not thought of that. It is not in the manual, is it?:)

Is it not? Then I wonder what sections 12.1.6 and 12.1.11 are for Roby? ;) I grant you that is does not cover the exact question of how do I place one ground poly exactly over the top of another but it gets the gist over :)
