How to split a polygon by an overlapping line feature

Here is a tip to split a polygon by an overlapping line feature. I have tested it in ArcMap 9.3 and it works.

· Select the polygon.

· Set the task to Cut Polygon Features.

· Click the Sketch tool.

· Right-click the line and click Replace Sketch. This lets you see the line's vertices and segments as an edit sketch.

· Finish the sketch (you can press F2 so you don't inadvertently add more segments to the sketch when you finish it). The polygon is split where the line crosses it.
