Is there any way to Export BPM Processes to visio or BPEL.
In Service Studio, you can open the process you want to export.
Then access "Module" -> "Export" -> "Process To Image":
That will export a png with your process logic.
Regarding other format, as far as I know there is no option for that.
If you really need such kind of export, eg. BPEL, it should be possible to build it using the BPT/BMP metamodel just like you can see a graphical example when you go to the Business Activity Monitoring component.
