In Astah, you can adjust lengths of lifelines and ExecutionSpecifications in UML Sequence diagram easily. You no longer adjust those lengths one by one. You can adjust them all once before you export diagrams to image files or print them out!
Adjusting ExecutionSpecification length
Right-click on diagram and select [Adjust ExecutionSpecification Length].
All the ExecutionSpecifications will be shown as shortest as possible.
This menu exists on context menu of each execution specification if you want to adjust the size of specific ones by choosing them.
Adjust Lifeline’s length
To adjust Lifeline’s length, right-click on diagram again and open its context menu.
You can choose how to adjust them from three options below:
- Default — All lifelines will be shortened as shortest possible
- Align to Minimum — All lifelines will be same length as the shortest one
- Align to Maximum— All lifelines will be same length as the longest one
This is the figure after choosing [Default].
Try these options to make it easier to clean out your UML Sequence Diagrams!
