One of the challenges of large, complex designs is tracking both the content and the changes to that content. Design history provides tools to make these tasks easier. They include:

• Isolate History by Fence or Selection, which shows the history of selected elements.
• List filter, which lets you filter the history list by selected criteria.
• Show revisions in reference files, which displays the history of attached references that have design history.
• Fit view (Zoom to Changes), which lets you zoom to selected changes in the models. Clicking this view control will switch models, if necessary, so that you can see the selected elements or revisions.
