You can create an initial node by selecting it from the tool palette.
If you’d like to allow only one initial node in a diagram, go to [Tools] – [System Properties] – [UML] and enable the option below:
※ This option is not available in Astah System Safety.
You can create an action just by double-clicking on a diagram or any other ways that are described in the Diagram Editor page.
You can also insert an action by placing a new or existing action directly on the transition line.
By default, actions won’t appear on the Structure Tree. So in order to show them in the diagram, you need to change the setting from [Tools] – [System Properties] – [Project View].
You can find this option from [Tools] – [System Properties] – [SysML] – [Project View] in Astah System Safety.
You can show Actions in the tree view, however, you cannot drag it to diagram from the tree view.
You are able to switch actions to any image files you upload to Astah.

Call Behavior Action is a call action that invokes a behavior directly rather than invoking a behavioral feature that, in turn, results in the invocation of that behavior. The argument values of the action are available to the execution of the invoked behavior. The execution of the call behavior action waits until the execution of the invoked behavior completes and a result is returned on its output pin. In particular, the invoked behavior may be an activity.
From the tree view, drag the Activity diagram to another opened Activity diagram to insert the Activity diagram as a call behavior action.
Or, you can select which Activity diagram to be associated with a call behavior action from the [Action] tab on its property view.
Create an Action, and adding <<process>>, <<signal receipt>> or <<signal sending>> stereotypes to the action will automatically change the notation.
After version 9.1, you can set Represents to Partitions.
