Using General Diagram Elements
In all diagrams, you can use borders for graphical groupings and comments and annotations for communication.
Creating Rectangle for Graphical Grouping
You can create a rectangle for graphical grouping using drag-and-drop.
The rectangle is purely a graphical element and is only used for the grouping. It can be found above the other elements and does not have the other owner properties typical to the elements in it.
Commenting on Elements
You are best off using comments for making notes about elements. You can use drag-and-drop to drag the comment template from the gallery and drop it on the model element to be commented on in the diagram. The comment is placed in the diagram and linked with the element by a dashed line. You can enter the comment text directly.
Creating Annotations
You can add annotations for all diagram elements. You can create annotations without access rights and in Read-Only Mode. Those editing the diagrams use annotations to communicate with each other.
Select the diagram elements you want to link to an annotation and select New Annotation in the context menu or drag the selected element into the open diagram area Show Annotations.
The annotation is created and can be seen along with information about which user wrote it and a timestamp. Click in the annotation and enter your text. The annotation is automatically saved.

You can store any number of descriptions for each model element, show them in the respective model element's specification preview.
Select the model element you want to describe.
Select Design>Edit>Specification (F3). The model element's specification window opens. Enter the element description.
Use the description text to
- Create Model References
- Insert hyperlinks to external targets
- Format text
Note
The number of tabs for specification texts and their names are set in the configuration.
Save the specification with Text>Specification>Save (Ctrl+S). If the specification text is saved, the name of the text definition being edited is shown in black.
