Use case

You might cut a polygon representing a large parcel to subdivide it into smaller parcels.

How to use the sample

Click the "Cut" button to cut the polygon with the polyline and see the resulting parts (shaded in different colors).

How it works

Pass the geometry and polyline to GeometryEngine.Cut to cut the geometry along the polyline.
Loop through the returned list of part geometries. Some of these geometries may be multi-part.
