Hi Peter!
Indeed, this is a valid point you are making.
Each trachel shape has a path, it should be possible to compute the center of it right? Is this what you are trying to do?

I am now working on a solution for our heavily modified dynamic multiline, so maybe the solution would be applicable also for the lines in roassal.
