How can I rotate swimlanes in Visio 2013 once the diagram is completed? That is, how do I switch swimlanes from horizontal orientation to vertical, or from vertical to horizontal? Here's an example diagram: 
For a new diagram, I know that swimlanes can be easily rotated with Cross-functional flowchart | Arrange | Orientation. The problem is when you have finished a diagram (e.g. a BPMN diagram) that has many objects contained within the swimlanes. When you rotate the swimlane orientation, the objects contained are not easily rotated--the result is quite a mess that you have to clean up: 
In short:
The result is not the automatic vertical rotation that would be expected; it is rather messy.
Is there a way to get a clean, [mostly] automatic rotation?

That did the trick for me, Good luck!

I tried to select the swimlames by clicking on each one with my mouse with the Ctrl key on the keyboard depressed, but it's almost the same messy result as I described in my original post with Ctrl-A. Could you please clarify if and how you got a better result?
Commented Feb 4, 2016 at 15:49I did a area-mark, one corner of the work area and then one on the opposite site so all swimlanes were marked, ctrl-a gives the same result. Then I used the orientation function on the cross-functional flowchart tab. I just did it on a larger swimlane chart than the last one and it works to change to horizontal and then back to vertical for me at least without messing up the looks of the chart. How do you make the transition to vertical/horizontal?
