One-Line Diagrams can be very large drawings, and being able to navigate them effectively is of great benefit when editing the network. In some cases, you may want to magnify one part One-Line Diagram, while at other times, you may want to see the entire
One-Line Diagram at once. The One-Line Diagram offers several tools that you can use to navigate even very large One-Line Diagrams quickly.
3.5.1. Scrolling a One-Line Diagram
You can use the scroll bars found along the bottom and right edges of the One-Line Diagram to move or “scroll” the One-Line Diagram in the viewport. The position of the scroll box in the scroll bar represents the position of the viewport relative to the
boundaries One-Line Diagram: to move the viewport to the right, move the bottom scroll box to the right, and so on.
Scrolling a One-Line Diagram does not affect the level of magnification. To scroll a One-Line Diagram
• Do one of the following:
To Do This
Scroll slowly in any direction Click the arrow in the direction you want to scroll: , , , .
Scroll quickly in any direction Click inside either scroll bar to move the scroll box in the direction of the mouse pointer.
Move to an approximate location on the One- Line Diagram
Drag either scroll box to the location you want. You can drag both the vertical and the horizontal scroll boxes.
Auto-Scroll Feature Drag the cursor or any component with the left mouse button depressed to an area just short of the one-line window edge. Holding your left mouse button depressed while the cursor is in this small "hit area" will
automatically scroll the drawing area. This is particularly useful when dragging a
component beyond the visible drawing area.
You may have noticed the grey-colored gridlines that crisscross the One-Line Diagram. These are page guides, and indicate where the page breaks will fall on the final printout in the "tiled" printing mode. Knowing where the page breaks are can help you group

components on a single page, make sure that textblocks do not fall on a page break, and so on. Page guides appear as dashed lines in the viewport, indicating the location of page breaks. Page guides do not print, even when they are turned on; they are used strictly as guides to help you lay out the One-Line Diagram. The page guides have no affect on printing is the "shrink to fit" printing option is selected.
You can turn the Page Guide on or off, and control where they fall, using the Page Layout command. Doing this, though, only controls the grey-colored gridlines. It does not control your printer’s output (that is done using the Print Setup command). You must ensure that the Page Guide specifications match the paper size selected for your particular printer, or the lines are useless. For example, you can set the Page Guides to 5-inch by 5- inch, and the lines will appear onscreen with those dimensions, but if your printer’s output is set to 8.5-inch by 11-inch paper, the lines will give you erroneous information about where the page breaks will fall. In addition, if you choose Landscape as the paper orientation in the Print Setup dialog box, the Page Guide width and height specifications have to be manually reversed to accurately show onscreen where the page margins will fall. For example, if 8.5-inch by 11-inch paper is selected as Landscape- instead of Portrait-oriented, you need to manually type 11 in the Width box and 8.5 in the Height box (essentially reversing them) for the Page Guide lines to accurately represent Landscape-oriented paper.
3.5.2. Magnifying a One-Line Diagram
You can use the One-Line Diagram’s zoom functions to magnify portions of the One-Line Diagram, and to move rapidly from place to place on large One-Line Diagrams.
Zooming In and Out
To enlarge the size of the One-Line Diagram relative to the viewport, use the Zoom In command. Each time you use the Zoom In command, you enlarge the One-Line Diagram incrementally from the normal 100% zoom size. To use the Zoom In command, click the Zoom In button from the Toolbar , or choose Zoom In from the View Menu (CTRL+Z). You can repeat the Zoom In command until the One-Line Diagram reaches a maximum magnification of 300%.
By default zoom in magnifies the One-Line Diagram in 20% steps, relative to a zoom factor of 100% (that is, 100%, 120%, 140%, and so on). If you want, you can change this zoom step at any time using the following procedure. Note that the zoom step is a global variable that affects all projects.
To change the zoom step
1. Click the Project>Options command.
