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).
