Target layer: Polyline

Description:  If switched ON draws at the end point of each polyline an arrow displaying the direction of the polyline. The size and color for the arrow symbol can be set in the ET GeoTools Control Panel - Draw Tab. The location of the arrow can be set to the End of the polyline or the Middle of the last segment of the polyline.

The user can adjust also the maximum number of visible features  for which the arrows will be 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: 

• Nothing much. A good alternative for the directional line symbol allowing quickly to be switched ON and OFF.
