How to rotate a pool in BPMN language?

Hello
I want to line up pools vertically.
Can you help me please?

as far as I can tell this is not possible, not because of Bonitasoft, but because the underlying eclipse software doesn’t support it…

It is possible to resize the pool so it becomes vertical but you will not be able to use lanes to divide it vertically.

Actually this is a limitation of Bonita BPM Studio as the BPMN specification illustrate such kind of design (page 306 - Figure 10.123)

Thanks for this answer.
