I am extremely frustrated right now. I have to cut out areas from a forest cover shapefile ("Existing Forest") and cannot do it. I am using templates. Here's what I do:
1. Start an editing session
2. Start the snapping toolbar and pick the vertex snapping button
3. Pick the layer's template, the polygon tools become enabled
6. Use the Straight Segment tool to draw the polygon defining the area to be removed.
7. Finish the drawing
8. Stop and Save edits. Re-start editing, select and delete the drawn polygon. It disappears, but the surrounding polygon is not cut because the deleted polygon overlaid it, it was not cut into it.
So, what am I doing wrong? The "donut hole" entries in the forums seem to all be for 9x. In 9x one could pick a cut polygon task, which worked nicely, but that has been removed in 10. Do I have to create a new polygon feature and use that to clip the Existing Forest layer?
Thanks for any help.
