Hello
I have found a solution to my problem.
Unfortunately, the command "Create Routes" requires a corner for the beginning of a route (Coordinae Priority), although it should be an optional subroutine. If you have several terrain cuts from different directions (e.g. corner up/left to down/right and vice versa) you have to take into account that the output values in the table will also be reversed.
Someone might have a solution that it always works no matter how the terrain cut is applied.
I hope the next one will have to think less than I did.
