How do I change where database diagram relationship lines attach in MySQL Workbench? Sometimes, MySQL Workbench makes some strange choices about where table relationship lines get attached.  For example, two vertical lines would be better in the following:



For a while, these boxes (representing tables) had two vertical lines between them, and the crossover happened when other boxes were added elsewhere in the diagram, and things got moved around a bit.  

Is there a way to say something like "this line should go to this attachment point"?
No, it's not possible to specify attachment points. That layout algorithm has a few flaws.
