Hi, we have received many emails asking for how to create Compositions and Aggregations on Astah UML Pad, so here is how to do so.

1. Create an Association line
2. Tap the target line (More like holding it for a second might work)
3. Three icons appear




4. Tap the blue icon




5. Then it gives you the options to modify the target association line including Compositions, Aggregations and multiplicity








Hope it helps.

Cheers,
SJ
