Viewing the Index Grid Layer
Maps such as city and road maps often use a map index to assist the reader in finding specific locations. An index grid is superimposed over the map and is typically annotated with letters and numbers around the edges of the map border. For example, many map readers are familiar with finding a road located in grid cell “G-4.” The Ortelius Index Grid, visible on the Index Grid layer, has flexible control for adjusting grid cell spacing, border styling, colors, and more.
The Index Grid is visible by default when a new drawing is created. Hide the Index Grid by selecting it in the Layers drawer and clicking the “eye” icon.
Changing the Index Grid Settings in Drawing Setup
Edit Index Grid settings by opening the Drawing Setup window (File > Drawing Setup) from the main menu. Edit left, right, top, and bottom Index settings. Turn on and off Annotation, Borders, change from Letters to Numbers, and edit grid settings and color.
Note, the index grid is dependent on the map scale and affects other derived objects such as Scale Bars.
