Answer 1

Hello E.,

To achieve this:

Source:

• https://stackoverflow.com/questions/49587971/can-i-create-a-nested-activity-diagram-in-uml

You can use sub-diagram as:

@startuml
:Action 1;
: Activity 1
{{
mainframe Activity 1
start
:SubAction;
end
}}
;
:Action 2;

If that can help,

Thank you. 

Can you tell me how to achieve something like that here?

Hello E.,

For that, you can use:

1/ Sprite, as:

@startuml
sprite $Invocation [16x16/16] {
0000000000000000
0000000000000000
0000000FF0000000
0000000FF0000000
0000000FF0000000
0000000FF0000000
0000000FF0000000
000FFFFFFFFFF000
000FF00FF00FF000
000FF00FF00FF000
000FF00FF00FF000
000FF00FF00FF000
000FF00FF00FF000
000FF00FF00FF000
0000000000000000
0000000000000000
}
start
:Action1;
:Action2:
Model2
\t\t<$Invocation>;
:Action3;
end
@enduml

Adapted from:

• https://forum.plantuml.net/15260/hide-complex-state-decomposition-reuse-state-machines?show=15272#c15272

2/ or Unicode, as:

@startuml
start
:Action1;
:Action2:
Model2
\t\t₼;
:Action3;
end
@enduml

If that can help,

Hello there,

A more scale-friendly alternative to the previous answers, using SVG:

' CallBehaviorAction (activity vs. action)
' (adapted from https://github.com/plantuml/plantuml/discussions/1066)
' SVG adapted from https://www.svgrepo.com/svg/412621/harvest
' (https://www.svgrepo.com/show/412621/harvest.svg)
sprite calBehaviorAction <svg viewBox="0 0 32 32" xml:space="preserve">
<path d="M26,14v14h-4V18h-4v10h-4V18h-4v10H6V14h8V4h4v10H26z"/>
</svg>
' Example of use
':Activity name\n                    <$calBehaviorAction{scale=0.5}>;
' Put as much space as needed so that the the symbol becomes correctly aligned.

start

:This is an action;
:The next element
   is an activity;
:An activity can be seen
as an abstraction level
  of a set of actions <$calBehaviorAction{scale=0.5}>;
:Hope that helps!;

stop
