Modeling inter Projects communication

​​If your model has more than one project and you want to make them communicate, you have to modify both projects.

Example:

Project1 sends a flow to project2, then project2 realizes an activity.

For example, project Train sends data to project Signage.

This can be resumed by this sequence diagram:

But in the model, we can only create sequence diagrams focused on one project.

Project2 is seen as a part of Environment by Project1, and vice versa.

In project1, we create a flow to the environment:

In project2, we create a flow from the environment:

For the simulation, some change might be needed:
