After having a closer look at the area charts mentioned above, it seems that these transit routes do not have crucial information published regarding the points that these routes follow. In the case of Bern, the North transit appears to not be a direct line between VOR/DME, but actually has a turning midway through which does not have its coordinate point specified.

Basically, to have anything included in the SkyDemon chart it is necessary for all precise coordinates to be officially published, particularly for building routes... Otherwise we would be forced to speculate and only draw them roughly, which is unacceptable. Until the day that Skyguide decide to actually publish these coordinates, we cannot proceed - As my colleague Tim mentions, reverse engineering charts published by third parties is not good practice.

However, fortunately, we are able to georeference the area charts from Skyguide, so at least it is possible to overlay them on the map and adjust your planned route visually. Hopefully this will satisfy your needs until the official data providers can effectively provide the data (rather than simply drawing a line on the map).

Unfortunately, the are chart of Geneva does not show the complete transit routes Sad

I do not think that Skyguide will provide the coordinates since these routes "are not exactly defined" (according to the answer which I receive from Skyguide).

Since they are not exactly defined, we could probably make up our own routes. Nobody could be scolded for flying them, because there is no exact definition to differ from.

I am joking of course, but it just highlights how silly this situation is.

I noticed yesterday that the Swiss VFR transit routes are now shown on SD: great job team Tim! 
Thanks again for a great product: I still regularly  discover features I hadn't noticed before, the last one being the local QNH shown at the top of the radio tab.

Cheers,
Alexis

Hang on: is it normal that these VFR Transit routes only appear when a route has been traced and don't when no route is created? (See screenshots) Am I doing something wrong, is it meant to be this way or is that a bug? 
Thanks, Alexis

Check your dynamic decluttering settings. The routes have quite high minimum altitudes so they'll be clipped out if you're hiding features above 4000 feet (for example).

You're absolutely right Tim. How daft of me. Thank you.
