Trimming line features (Defense Mapping)

The Extend/Trim Selected Line With Edit Sketch tool allows you to extend or trim a line, respectively, by drawing a sketch in the map. If the sketch crosses the selected feature, the feature is trimmed. The starting point of the sketch determines which part is trimmed. If the sketch starts above the feature, the left side of the geometry is trimmed.
