Export all models as BPMN

Hi, 

I am using a newer version than you- however, I am quite sure that this feature has been available for some releases:

you need to make sure that all of the models are in one folder. Then you can tick the checkboxes of each model you want to export as bpmn. Go to Export and export as bpmn. All selected files will be exported as BPMN (even though the dialogue is a bit confusing).

Hope this helps :)

Best,

Veronika
