• 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.

Aligning the grid

In a ground poly tutorial (2014+) one of the steps is aligning the grid in gmax so the runway (and therefore whole airport) orientation is on the nice 90 degree angle so modeling ground polys is much easier. In Blender I can't find any similar settings or function that could do the same thing. Is there any good solution for this in Blender? The only thing I came up is rotating the whole thing at the beginning (background and all ground polys) so the runway is straight and at the end when all ground polys are modeled rotate the whole thing back for exactly the same degree. Would this work or is there a better solution?
 
As far as I see in GMax it only alignes the view to the local object's rotation.
You can do it in Blender by simply selecting an object (e.g. a runway plane that has an axis along the runway direction) and pressing Shift+7.
 
That just rotates the view (aligns it to active object).. the whole grid is by an angle and every new object that is created is created by an angle. I think the gmax method also aligns the grid itself so making ground polys is easier so you don't have to rotate every single new poly so that is matches the new orientation.
 
I wonder if that is neccessary in Blender. Whole different workflow. Probably a Gmax groundpoly designer can clear up things, why it is done?
 
As I understand correctly it's done because it's much easier to draw lines (taxiway, runway,..) straight than by an angle. If you import hi-res ground texture for airport background it's imported by north-south orientation and not all runways/airports are orientated 0-180. So you either have to draw ground polys (lines, markings,..) by an angle or you rotate the whole thing so it's straight and you have much easier job. I don't know how different workflow would solve this.
 
I don't see a problem drawing the things at an angle. They can still be transformed along local orientation.
 
It don't want to say it can't be done but wouldn't be easier if you don't need to rotate every single polygon you make? If you make hundred that would mean hundred more steps for example, also making curved polygons at an angle, taxiway edge lines that have to match on both sides for example, is probably harder than making them at round angles (90, 180). There must be a good reason that gmax technique includes this step, right?
