Use the Summary Pane

You can view the net result of changes made to a model in the Summary pane. The top level node in the tree displays the text Session Summary next to it. Below this node, changes made to a model at the object level and property level appear in the tree. When the model is updated, the changes reflect in the Action Log.

To switch to the Summary pane, click the Summary tab at the bottom of the Action Log pane.
