Webel: MagicDraw/Cameo: UML/SysML: TIP: Activity Diagrams, StateMachine Diagrams, and port-based IBDs: Keep it loose initially with oblique (no break) paths, then square it up with rectangular paths at the very end

When diagramming, don't obsess about aligning rectangular paths early on, especially when dealing with connections between Ports and edges to Pins. Keep it loose initially with oblique paths until your diagram is more stable, then "square it up" if you wish by converting the path to rectangular form.
