Edit Exit Panel Dialog Box

This dialog box displays when the exit panel has a replaceable field.

Replace the 'X' component with the desired exit number or message, and then press TAB to update the exit panel preview.

The Letter spacing and String length parameters can be set to the desired values similar to using the Advanced parameters of the Place Highway Text and Edit Highway Text tools (see Place Highway Text -> Advanced).
