This will draw the polylines on the layer three times in three different ways to create the visual effect of a highway with a center line. Online Help Index polygon layers styles Styles area in the Styles tab of the Map Layer Properties dialog box In the preview box, the right half of each style shows the style you specified for it, and the left half of each style shows the cumulative effect of drawing that style on the previous style (the first style in the list is drawn first, the second style is drawn on top of that, and so on). Thus, the left side of the last style shows you the final style that will be used to draw the polylines on the map. To create another style, click New in the Styles area, and then specify the line style, color, and width that you want to appear on top of the existing style.
