• 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.

Heading of polygon

Hi Arno!

Quick question for the boss ;)

Does ScenProc have a function to find out the heading of an nearly rectangular polygon?

Example:


I would like the direction from the line marked with the arrow.
I don't really care from which side it is measured, whether it is 340 or 160°... The main thing is the direction of the longest side of a polygon.

Does ScenProc have such a feature, and if not, does anyone have an idea how I can solve this in Python/ArcGIS?

Hi,

I need to check the code. In steps like PolygonToPoint I have such logic. But I need to check if you can access it as an attribute as well.

Hi,

It's available already, the special attribute FHEADING gives the heading. I'm not 100% sure if I use the longest side though, so it might be 90 degrees off.
