The org chart supports two basic element types: Roles and Connectors. The roles can be of three kinds:
The hierarchy is organized from superior to subordinate in the following directions: from top to bottom and left to right. Connector lines link the superiors with subordinates.
You can insert the roles using the drag&drop from the toolbox or clicking the respective button in the context bar. You can also use any other common way for all the diagram elements in Software Ideas Modeler.
If you have an existing hierarchy in the text form, you can generate the whole organizational chart in a few clicks. Just follow the instruction in this article about tree diagram creation.
Choose the Organizational Chart in the Diagram type drop-down and paste the hierarchy into the Definition text box. After clicking the OK button, the diagram of the given organization will be generated and added to the project.
