When you open a model from the explorer tree, 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 Pane

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
(see Managing the Diagram Pane for details).
The Execution Pane is displayed below the diagram pane
(see chapter Modeling Execution for further information).
Three Designer Panels are shown in the left sidebar
(see Managing Panels for details):
- The Service Panel
- The Attributes Panel
- The Validation Panel

Modeling on the Diagram Pane

Action	Example	Description
Navigation		You can use the Overview Panel to navigate in your BPMN model. The panel displays your model and a blue frame, representing the content shown on the diagram pane. If you want to work on another part of the model, you can use the frame to quickly change the display.
Zoom		When modeling, you have several options to apply the zoom on the diagram pane. Press the Ctrl button and use the mouse wheel. Use the zoom bar at the bottom of the pane. To zoom, you can use the pin or press the plus or minus button of the zoom bar.
Zoom		You can also use the Overview Panel to zoom in or out the model: Hover over the right bottom corner of the blue frame. The cursor changes and you can resize the frame.

The Diagram Context Menus

Various context menus support the user during modeling on the diagram pane:

If you create a new element using the context menu, the relation to the current element is drawn automatically.

Tools Context Menu

If you right click on an element, the tools context menu opens. Use it to edit the current element.

The following options are available:

Icon	Description
	Delete the element.
	Copy the element.
	Cut the element.
	Paste format of the element.
	Bring the element to the front.
	Send the element to the background.

Extended Tools Context Menu

If you have selected more than one element on the pane, the tools context menu is enhanced with additional options:
