Using the zoom facility
You use the zoom facility in Modeler to view a diagram in more or less detail. You can set the zoom level to define the area on the active diagram that you want to zoom in on.
You can use Fit symbols to View to optimize the screen display by displaying the diagram in the largest possible scale available for the open window. This feature is useful if you have been zooming in and out to areas of the diagram and you want to see the diagram in its entirety. Note that if any items are selected on the diagram, the Fit symbols to View command displays the selected items in the largest possible scale.
Note that you can zoom in and zoom out of the diagram through the Diagram Thumbnail pane. For more information, see Using the diagram thumbnail pane.
