Flipping labels when section view view direction changes

[dirk_brus]

Hi,

I think it's a long shot, but does anyone have an idea to create flipping labels for a corridor when the view direction of a section changes? For example: I have a road design and i would like to show driving direction arrows. the setup is a corridor with 2 baselines (dir. North and South), so i have (sort of) the same assembly that i use in both directions. When i take sections of the design it would be handy that i have arrows pointing the correct direction (up or down) (see picture below).

I haven't tried it but, if your right lanes are ALWAYS right of the baseline and your left lanes are ALWAYS left of the baseline, you may be able to create an expression that rotates the arrow. If the offset is positive, rotate 0, if the offset is negative, rotate pi (i.e. 180 degrees).

Problem is that my assemblies are always on the right of their baseline. the sections are taken over a third (central) alignment. so their is no clear link between the section view and the positioning of the corridors, i think.

Maybe if there is a way to define a label connected to a corridor that can define if you are looking "upstream" or "downstream" of the baseline alignment. and this in any section view, even when the sample line is connected to another one besides the baseline.

i think it's not possible, but i can try to reach out to you guys... 😄
