Im trying to a block diagram with some blocks nested within a top level box, the lower level boxes need to have multiple connections between them but Visio's auto connection feature is hindering that, another problem is that the tool will only let me draw a line with no more then one right angle. 

Is there a way to turn off the auto-connect feature?
