Navigating diagrams
System Architect XT converts diagrams from your encyclopedia into the SVG image format. Diagram images can be magnified and minimized with the icons at the top of the diagram. Additionally, the diagram can be panned in all directions by clicking the mouse over empty diagram space and dragging, or using Ctrl or Shift key combined with clicking the mouse to force pan, rather than opening a link when clicking over symbols that have an embedded link.
