• 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.

P3D v4 Boolean possible with planes?

Hi,

here again the Master of unanswerable questions :p....

Just thinking about some experiences with groundpolygons and would like to ask if it is possible to use two planes for a boolean cut. Idea: Using the taxiway/road poly to make a boolean cut into a grasspoly layer. After this, I could raise the top of the cut grasslayer a little to make a 3D-object out of it (for example for snow...) that makes the airfield look more real. Or is there some other solution like that? Just a thought....
 
With GMAX I use 'shapemerge' for that sort of thing, just create your shape -- such as a rectangle, etc, or simply draw your own. 'Merge' will add your shape geometry, and 'cookie cutter' will cut a hole.
Be aware that you can get some overly complex results unless you are careful.
 
I’d suggest making sure both shape and ground poly are Editable Poly before you do. In normal boolean operations this reduces the number of extra vertices generated.
 
Good advice, Tom, thank you. Yes, I create all my polys like that. Some months ago, I did some planes as mesh and had some issues indeed while converting.
(BTW: I like your signature - unbelievable that we were kings with those features :D...)
 
I found that boolean does not work as expected especially 2D objects like ground poly. So, I select the border and click on create shape (do not select smooth) then you get editable spline and do the boolean from that. After you are done, turn it back to editable poly. You need to make sure that all the vertices of the spline are at the same level in height to make boolean spline works.
Please take a look at my tutorial in Wiki "Ground poly for the year 2014+"
