Defining Custom Views
The Visualize toolbar has a a dropdown list and several buttons that can be used to quickly snap the 3D View to a specific orientation relative to the global axes. Clicking on one of those buttons, or selecting one of the many options in the dropdown list immediately changes the orientation of the 3D view (e.g., side view, from top, from back, etc.).
The three custom views at the bottom of the dropdown option list allow the user to customize a specific view that can be snapped to this orientation with a single click.
The user can also set the three "Custom View" options in FRED's Preferences by selecting Tools > Preferences from the menu. On the Visualization tab, the user can 1) enter the camera position/orientation manually, or 2) click on the Get Current View button to import the data for the current view.
