To access the Preferences dialog, click the Settings button in the upper right corner of the map and select Preferences from the menu that appears.

The Preferences dialog allows you to:

• Set the desired snap Tolerance and Unit
• Set the Preferred Linear Referencing Method
• Set the default linear measuring unit when using the measure length tool
• Define the “buffer” (in percent) in the extent the map will zoom to, when zooming to a feature from the selection/search results dialog. So, if for example this value is set to 5, when you zoom to a line or polygon feature, the map will not zoom to the exact extent of the feature but to the extent created using a buffer 5% larger than the original extent
• Control whether directional arrows will be used when editing network and asset data
• The Min Zoom to Scale controls the minimum scale the map will zoom to, when zooming to point features
• The Search Extent Min char value defines the minimum characters to trigger the search within the various autocomplete textboxes when searching/filtering for network elements (e.g. Advanced Search->Network Filter, Asset Maintenance Form->Network Unique/Save Extent, Asset Forms->Create Location/Relocate, etc)
• Set the style (color, width, style) for the various edit and selection actions

Each panel includes a preview of the style, shown on the right.

You can expand or collapse any style panel as needed. Click the Plus button to expand a panel and the Minus button to collapse a panel.

When you have finished setting the preferences, click OK. A success message appears briefly onscreen.
