Working with the BPMN Editor
When you open a model from the service panel, a second tab will open, displaying the model on the diagram pane. This is where you design your BPMN model.
The diagram pane consists of different areas:
Customizing the Diagram Panel
You have several options to adjust the diagram pane. When you open the pane for the first time, the default view is displayed:
The Diagram Pane is displayed in the centre at the top
(refer to chapter Modeling BPMN for further information)The Execution Pane is displayed below the diagram pane
(refer to chapter Modeling Execution for further information)Four Designer Panels are shown in the left sidebar
The Service Panel
The Controls Panel
The Attributes Panel
The Validation Panel
Refer to Customizing Editors and Panels for detailed information about panel management in general.
Modeling on the Diagram Pane
While modeling, some general functionalities help you to browse through your model, and to adjust your working location within the model. Refer to Customizing Editors and Panels for more details.
In addition to the standard panels that are active by default (like e.g. Attributes Panel or Validation Panel), the BPMN editor comes with an Overview panel. Activate this panel by clicking its icon in the top right corner. You can use this panel to navigate in your BPMN model. This is useful when the BPMN model is large and expands beyond the visible canvas.
The Overview Panel displays your model and a blue frame, representing the content shown on the diagram pane. If you wan to quickly change your working location in large models, you can move the frame to change the visible part of the model:
You can use the Overview panel to zoom in or out of the model. Hover over the right bottom corner of the blue frame. The cursor changes and you can resize the frame:
Refer to Customizing Editors and Panels for detailed information about panel management in general.
The Toolbars
Two toolbars are available for work on the diagram pane:
The Model Toolbar
The model toolbar assists you during modeling on the diagram pane:
Enabled options are highlighted in blue:
The following table explains all available tools:
Tool Icon | Tool Name | Description |
|---|---|---|
 | Export | Use this option to export your BPMN model in JSON format. |
 | Share | If you use option Share, the URL of your BPMN model is copied to the clipboard and you can paste it elsewhere, for example in an email. |
 | Hide Execution Pane | Use this option to hide the execution pane. This allows to gain more space during modeling. |
 | Toggle grid | Use this option to enable or disable the grid on the diagram pane. The grid supports you during modeling: If the grid is enabled, elements snap to the grid points. |
 | Insert/Remove horizontal space | Use this option if you need more or less space on the diagram pane. Click on the pane to display the start line, the second click marks the end line and defines the size of the area to be added. To add space, click from left to right to define the area. If you want to delete a horizontal space, click from right to left to define the area. |
 | Insert/Remove vertical space | Use this option if you need more or less space on the diagram pane. Click on the pane to display the start line, the second click marks the end line and defines the size of the area to be added. To add space, click from top to bottom to define the area. If you want to delete a vertical space, click from bottom to top to define the area. |
 | Undo | Undo the previous action you performed in...
If you click Undo in one of the Designer editors, this may also have an effect on the Implementation folder in the Service panel if you performed your previous action there. |
 | Redo | Redo your previous action (after undo). |
The Elements Toolbar
The elements toolbar contains all BPMN elements that you can create on the diagram pane. By default, the elements toolbar only displays the icons of the available BPMN elements. But you can also expand the toolbar using option Collapse at the bottom. In its expanded version, the names of all elements are also displayed:
In chapter Supported BPMN Elements all elements and their specific properties are described.
Drag the element you want to create from the toolbar and drop it on the diagram pane:
Another way to create a bpmn element is to click on the element in the toolbar, switch to the editor and click again. To cancel the operation, press the Esc key.
The Diagram Context Menus
Various context menus support the user during modeling on the diagram pane:
Elements Context Menu | Icon | Description | |
|---|---|---|---|
 | If you click on an element, the element context menu opens. You can use it to create new elements instead of using the elements toolbar. Choose one of the icons to create the corresponding element. If you create a new element using the context menu, the relation to the current element is drawn automatically. In addition to the BPMN elements listed in the context menu, you can create additional elements from the elements toolbar: These elements cannot be connected to others. |  | See End Event |
