The Navigation menu item on the block pop-up menu has three submenu items: Show Snapshot, Track Animation, and Show Connector Links. The features that are associated with these items are particularly useful when you work with large simulation models. Selecting Show Snapshot creates a new window that displays a scaled-down version of the entire model in the currently active model window. This new window is called the Snapshot window. The portion of the model visible in the original model window is depicted by a highlighted rectangle in the Snapshot window. You can drag the highlighted region in the Snapshot window to reveal other regions of the model in the associated model window.
When you run a large simulation model, the area of the model where the animation is occurring might not be visible in the model window. You can select Track Animation to enable the model window to scroll (when the simulation is running with animation turned on) to ensure that the part of the model currently being animated is always visible.
By default, the links between Connector blocks are invisible. You can select Show Connector Links from the Navigation submenu to display all connector links in the model.
