The Hole Cutter tool allows holes to be selected, cut and edited. The hole cutter has the following functionality:
- Clicking within an existing polygon will start the creation of a hole. Creating a hole is the same as creating a polygon using the Polygon Tool except that creation is restricted to within the polygon. Notice that the created vertex is within a selected polygon

- Clicking an existing hole will select it.
- Vertices in selected holes can be moved when in Advanced Edit Mode.

- Vertices in selected holes can be added when in Advanced Edit Mode.

- Vertices in selected holes can be deleted when in Advanced Edit Mode.

- As with the Edit Geometry Tool the vertex operations can be performed on multiple vertices at once if many vertices are selected.
