Created attachment 124117 [details] On Off Statemachine SUMMARY When I draw to states with a transition to each other. Th transition arrows are always one on top of the other. It is hard to separate the two arrow from each other by e.g. moving the start points and end points of those arrows along the state border. STEPS TO REPRODUCE 1. add a state diagram 2. add a state "On" to that diagram 3. add a state "Off" to that diagram 4. add a transition from "Off" to "On" with event trigger "Power Button" 5. add a state transition from "On" to "Off" with event trigger "Power Button" (=> the second transition arrow is on top of the first one) 6. try to separate both arrows to e.g. be parallel with a distance between them by moving the arrows ore the start points and endpoints with the mouse OBSERVED RESULT It's not possible to separate both transition arrows. EXPECTED RESULT It should be possible to move the start and end points along the state border and drag the the transition arrows.

A solution is to change the type of association line to 'Spline', which gives you control points for each line. This makes it easy to adjust individual lines. To use 'spline' association line type by default you can set "Create new association lines as" in the main page of the settings dialog. Please note that there is currently a bug with to setting the default line style mode. See bug 414520 for details, which has been already fixed in git branch release/19.12.
