Show All Redlines
Prior to showing all redlines, click on the Zoom To, Pan To, or Show only this redline button under any redline record to load the map service into ArcMap. Then, to display all the redlines currently listed, click the Show all redlines button at the top left of the redlines pane. The extent does not change, so you may need to zoom out or pan to see all the redlines. Clicking this button clears out any definition queries that might be applied to each redline layer.
