Activities and partitions (swimlanes and matrix)

[Paul V]

I would like to see your swimlane and matrix features found on activity diagrams also become available to within an activity.

Like this?

You find Partition Activity in context menu on any Activity element.

How did you get the matrix form in Activity2 in your example?

[Jan ´Bary´ Glas]

Create an activity and three partitions. Make the activity larger, move two of the partitions on the activity (it connects automaticaly), you might need to set activity appearance Z-Order to Bottom. Make the third vertical (context menu, Advanced, vertical partition) and move it over the activity as well.
