Model Structure Tool Window View

Purpose

The Model Structure tool window view shows the hierarchical structure of the model in the form of a tree. The respective structure content for each node in the tree is displayed in an area beneath it.

The model tree can be filtered by particular element groups. You can use a name filter in the structure content.

Both areas of the Model Structure tool window view are primarily used for navigation in the model.

Structure

The Model Structure tool window view consists of an upper model tree with a predefined filter selection for particular element groups and a lower structure content with name filter.

Use the Show Model Element List button on the right next to the Filter check box to open and close the Model Element List.

Model Tree

The model tree displays all structural elements of your model in a tree structure of the kind you will be familiar with from the navigation frame of Windows Explorer.

The structural elements of your model are:

System models
Models
Packages
Components

The model tree includes the following means for identifying items:

Expand icons before the item indicate sub trees ( (closed) or (open))
Bold text indicates elements that can be edited in editors (components)

The model tree has a predefined filter selection for particular element groups, which constrains the display accordingly. For the Diagrams filter, for example, only those structural elements that contain diagrams are displayed in the tree. The diagrams themselves are in the structure content.

Structure Content

The lower area, the structure content, is where you can find all the elements which are contained in the structure element selected in the model tree and

can either be opened themselves (diagrams, processes, classes, entities) or
can be used in diagrams directly by means of drag-and-drop, or are needed to edit the diagram, but are not directly shown in the diagram themselves (GlobalTask, data stores).

The structure content is sorted alphabetically and can be displayed as a list or in a hierarchical structure.

The display can be restricted using a name pattern in the <Browse Structure> field. When you restrict the display using a name pattern, it automatically changes to list view.

The structure content includes the following means for identifying items:

Bullet points indicate subordinate structure content
Bold text indicates elements that can be edited in editors

Filter for Element Groups

The model tree has a predefined filter selection for particular element groups, which constrains the display accordingly. You can use the following filters:

All Model Elements

Use the entire visible model.
Diagrams

Search only for elements that may be opened as a diagram or table.
Cross-sectional concepts

Concepts and whiteboards of generic usage.
Glossary

All glossary entries.
Requirements Model

Requirements Modeling results.
Business Model

Business Process Modeling results.
Process Model (BPMN 2.0)

Process Modeling Results in BPMN 2.0 notation.
Animation Paths

Path animation results.
Resources

Business Resources Modeling results.
Structure Model (UML2)

Object-oriented structure modeling results (UML 2).
Behavior Model (UML2)

Object-oriented behavior modeling results (UML 2).
Entity-Relationship Model

Results of the conceptual model.
Database Model

Results of the database schema.

Use

You can access almost all model elements from the Model Structure.

Elements which can be opened (e.g. diagrams) are shown in bold so you can recognize them more easily. You can open these in the structure area by double-clicking. Alternatively, they can always be opened via the ribbon ( Start>Open>Open (Enter)) or the context menu.

You can use most ribbon commands for the elements in the model tree. The context menu contains other commands.

The commands for importing and exporting model fragments (can be found under Model>Information) affect the model structure.

There are two navigation helps in the top half of the model structure:

You can use the Filter drop-down list to select a predefined element group, in order to restrict the display in the model structure accordingly.
Use the Show Model Element List button on the right next to it to open and close the model element list.
You can enter a name pattern in the <Browse Structure> field above the structure content to restrict the elements displayed there.

Drag-and-Drop in Other Areas

You can use the mouse (left mouse button pressed) to drag elements into other areas.

Elements can be dragged into the result region which adds them.
Elements can be dragged into an open diagram if they are allowed as contents in the diagram and do not already exist there.

Drag-and-drop from Other Areas

By dragging with the mouse (holding down the left mouse button), from the model element list for example, elements can be assigned to other owners if they are allowed as content there.
