Click on several polylines to select them. Click the Draw | Edit Boundaries | Create Line Intersections command to break the selected polylines into multiple polylines. At each location where two polylines cross, two separate polylines are created for each original polyline. The beginning and ending points for the new polylines are the location where the original polylines crossed. For example, if two polylines cross on a layer, four polyline segments would exist after using this tool.
