Hi Borislav,
thank you very much, this was the tip to success!
The odd thing about the line object: Once I save it, it gets write protected and the properties are frozen to the state of origin. So if you forget to check any box while generating it, you have to delete it and create a new one with the proper properties ;(>
P.s.: Sorry for the late answer, I was absent here for a long time!
