You can create an initial pseudo state by selecting it from the tool palette.
If you’d like to create more than one initial pseudo state on a diagram, go to [Tools] – [System Properties] – [UML] and disable the option below:
※ This option is not available in Astah System Safety.
You can create States just by double-clicking on a diagram directly. Or you can use other ways described in the Diagram Editor page.
If you want to insert a new state between States, just slide a new state on a transition line.
By default, States aren’t on the Structure Tree. So in order to show them, you need to change the setting in the System properties from [Tools] – [System Properties] – [Project View].
You can find this option from [Tools] – [System Properties] – [SysML] – [Project View] in Astah System Safety.
However, you cannot drag and drop a state to a diagram. If you’d like to reuse states, please copy and paste.
To add a region, choose [Add Region] from State’s pop-up menu and choose vertical or horizontal.
