Target layer: Polyline

Description:  If switched ON analyzes the polylines visible in the view for duplicates after each refresh of the screen and draws the exact duplicates if present. The symbol for the duplicate polylines can be set in the ET GeoTools Control Panel - Draw Tab. The user can also adjust the maximum number of visible features  for which the polylines will be analyzed and the duplicates drawn automatically after each operation that triggers screen refresh. If the visible features are more than the user specified amount, the command is automatically turned off. The default value for the Max Features Auto Redraw is 1000 features. This should work fine on an average PC, but it is entirely up to the user to set this value to any number if it does not slow down the refreshing of the screen. 

Advantages: 

• The command allows automatic identifying of the duplicates in a polyline dataset. Use Remove Duplicates Tool  to correct such problems 
• It is not dependent on the Topology introduced in ArcGIS 8.3 and can be used in any version of ArcGIS 8.1 and above
• Can be used with any license (ArcView, ArcEditor or ArcInfo)
